.. include:: /Includes.rst.txt .. _troubleshooting-editor-issues: ============== Editor Issues ============== Solutions for problems encountered in the TYPO3 backend editor and CKEditor functionality. .. important:: **Backend vs Frontend Issues** The **backend RTE** works automatically after ``composer require netresearch/rte-ckeditor-image``. For **frontend rendering issues**, ensure you've included the TypoScript. See :ref:`integration-configuration-frontend-rendering`. If you're experiencing backend issues, check: 1. Clear caches: ``./vendor/bin/typo3 cache:flush`` 2. Verify extension is activated 3. Check browser console for JavaScript errors .. contents:: Table of Contents :local: :depth: 2 Image Button Problems ===================== .. _troubleshooting-image-button-missing: Issue: Image Button Not Visible in Toolbar ------------------------------------------- **Symptoms:** * Insert image button missing from CKEditor toolbar * RTE loads but no image functionality **Causes:** 1. Plugin not properly imported in RTE configuration 2. ``removePlugins`` includes image plugin 3. Toolbar configuration missing ``insertimage`` item **Solution:** .. code-block:: yaml # Configuration/RTE/Default.yaml imports: - { resource: "EXT:rte_ckeditor_image/Configuration/RTE/Plugin.yaml" } editor: config: removePlugins: null # Critical: Don't remove image plugin toolbar: items: - insertimage # Add to toolbar ---- Style Dropdown Problems ======================= .. _troubleshooting-style-dropdown: Issue: Style Drop-Down Not Working with Images ----------------------------------------------- **Symptoms:** * Styles disabled when image selected * Style changes not applied to images **Cause:** Missing ``GeneralHtmlSupport`` dependency (fixed in v13.0.0+) **Solution:** Ensure you're using extension version 13.0.0 or higher: .. code-block:: bash composer require netresearch/rte-ckeditor-image:^13.0 The plugin now requires: .. code-block:: javascript static get requires() { return ['StyleUtils', 'GeneralHtmlSupport']; // Both mandatory } .. important:: The ``GeneralHtmlSupport`` dependency is critical for style functionality in v13.0.0+ ---- Issue: Custom Image Styles Lost After Upgrade ---------------------------------------------- **Symptoms:** * Custom styles no longer available * Style drop-down empty **Cause:** RTE configuration changed **Solution:** Re-apply custom styles in RTE configuration: .. code-block:: yaml editor: config: style: definitions: - name: 'Your Custom Style' element: 'img' classes: ['your-class'] ---- File Browser Issues =================== .. _troubleshooting-file-browser: Issue: File Browser Empty or Not Loading ----------------------------------------- **Symptoms:** * Modal opens but shows no files * File browser stuck loading **Causes:** 1. No file mount configured for backend user 2. Missing file permissions 3. Empty fileadmin directory **Solution:** .. code-block:: typoscript # User TSConfig options.defaultUploadFolder = 1:fileadmin/user_upload/ Verify backend user has file mount in: **Backend** → **User Management** → **Backend Users** → **File Mounts** ---- Issue: "File Not Found" After Selection ---------------------------------------- **Symptoms:** * Image selected but error occurs * Empty image inserted **Causes:** 1. File reference invalid 2. Storage not accessible 3. File deleted from filesystem **Solution:** 1. Verify file exists in ``fileadmin/`` 2. Check file permissions (readable by web server) 3. Clear file abstraction layer cache: .. code-block:: bash ./vendor/bin/typo3 cache:flush --group=system ---- Image Dimension Problems ========================= Issue: Magic Image Maximum Dimensions Not Working -------------------------------------------------- **Symptoms:** * Images not respecting configured maxWidth/maxHeight * Large images not being resized **Cause:** TSConfig settings in custom template extension not loaded (TYPO3 bug #87068) **Solution:** Add settings to root page config instead: .. code-block:: typoscript # In root page TSConfig (not template extension) RTE.default.buttons.image.options.magic { maxWidth = 1920 maxHeight = 9999 } .. tip:: Place TSConfig settings in root page configuration for proper loading. ---- JavaScript/CKEditor Errors =========================== Issue: JavaScript Console Errors --------------------------------- **Symptoms:** * Browser console shows errors * Editor doesn't load properly Common Errors ^^^^^^^^^^^^^ 1. "GeneralHtmlSupport is not defined" """""""""""""""""""""""""""""""""""""" **Cause:** Extension version < 13.0.0 **Solution:** Update to latest version: .. code-block:: bash composer update netresearch/rte-ckeditor-image 2. "Cannot read property 'typo3image' of undefined" """""""""""""""""""""""""""""""""""""""""""""""""""" **Cause:** Plugin configuration not loaded **Solution:** Verify ``Configuration/RTE/Plugin.yaml`` imported: .. code-block:: yaml imports: - { resource: "EXT:rte_ckeditor_image/Configuration/RTE/Plugin.yaml" } ---- Issue: Double-Click on Image Does Nothing ------------------------------------------ **Symptoms:** * Double-clicking image doesn't open dialog * Edit functionality not working **Causes:** 1. DoubleClickObserver not registered 2. JavaScript error blocking execution 3. Image not recognized as typo3image **Solution:** 1. Check browser console for JavaScript errors 2. Verify image has ``data-htmlarea-file-uid`` attribute 3. Clear browser cache and reload 4. Check CKEditor version compatibility (requires CKEditor 5) ---- Editor Loading Problems ======================= Issue: Editor Not Initializing ------------------------------- **Symptoms:** * CKEditor doesn't load * Textarea remains plain text field **Causes:** 1. JavaScript errors preventing initialization 2. RTE configuration not loaded 3. Browser cache issues **Solution:** 1. Check browser console for errors 2. Verify RTE preset is enabled: .. code-block:: yaml # Configuration/RTE/Default.yaml imports: - { resource: "EXT:rte_ckeditor/Configuration/RTE/Default.yaml" } - { resource: "EXT:rte_ckeditor_image/Configuration/RTE/Plugin.yaml" } 3. Clear browser and TYPO3 caches: .. code-block:: bash ./vendor/bin/typo3 cache:flush 4. Force reload in browser (Ctrl+Shift+R) ---- Plugin Configuration Issues =========================== Issue: Plugin Not Recognized ----------------------------- **Symptoms:** * Image plugin functionality missing * Console error about undefined plugin **Cause:** Plugin configuration not properly loaded **Solution:** Ensure proper import order: .. code-block:: yaml # Configuration/RTE/Default.yaml imports: # Base CKEditor configuration first - { resource: "EXT:rte_ckeditor/Configuration/RTE/Default.yaml" } # Then image plugin - { resource: "EXT:rte_ckeditor_image/Configuration/RTE/Plugin.yaml" } editor: config: # Ensure plugin is not removed removePlugins: null toolbar: items: - insertimage ---- Debugging Editor Issues ======================= Enable RTE Debugging -------------------- .. code-block:: typoscript # Page TSConfig RTE.default.showButtons = * RTE.default.hideButtons = Check Loaded Configuration --------------------------- Browser console: .. code-block:: javascript // Check if plugin loaded console.log(CKEDITOR.instances); // Inspect editor config const editor = Object.values(CKEDITOR.instances)[0]; console.log(editor.config); Monitor Network Requests ------------------------- 1. Open browser DevTools 2. Go to Network tab 3. Trigger image selection 4. Check for failed requests to: * ``/rte/wizard/selectimage`` * Backend image info API Inspect DOM Elements -------------------- Check if images have required attributes: .. code-block:: javascript // In browser console document.querySelectorAll('img[data-htmlarea-file-uid]'); ---- Resolved Issues ================ .. _troubleshooting-utf8-figcaptions: UTF-8 characters in figcaptions ------------------------------- .. versionchanged:: 13.6.0 **Symptoms:** * German umlauts (ä, ö, ü, ß) corrupted in figcaptions on the frontend * Accented characters (é, ç, ñ) replaced with garbled text * Only figcaptions affected, image alt/title attributes rendered correctly **Cause:** PHP's ``DOMDocument::loadHTML()`` defaults to ISO-8859-1 encoding, which corrupts multi-byte UTF-8 characters during HTML parsing. **Status:** Fixed. All ``DOMDocument::loadHTML()`` calls now prefix the HTML with ```` before parsing. No action required. .. _troubleshooting-inline-link-resolution: Inline linked images with unresolved t3:// URLs ------------------------------------------------ .. versionchanged:: 13.6.0 **Symptoms:** * Inline linked images show ``t3://page?uid=123`` as literal text in the frontend ``href`` instead of the resolved URL * Links work in the backend but not on the frontend **Cause:** The ``externalBlocks.a`` configuration was dead code — the ```` tag was never listed in the ``externalBlocks`` comma list, so the per-tag configuration was silently ignored by TYPO3's parseFunc. **Status:** Fixed. Link resolution now uses ``tags.a`` with a dedicated ``renderInlineLink()`` method in the ``ImageRenderingAdapter``. No action required. ---- .. _troubleshooting-known-limitations: Known Limitations ================= .. _troubleshooting-figcaption-line-breaks: Figcaption line breaks ---------------------- **Symptoms:** * Pressing Shift+Enter in figcaption does not insert a line break * Adding ``
`` in source mode is removed after saving * Caption text always appears on a single line **Cause:** CKEditor 5's ``figcaption`` content model only supports inline text — it does not allow ``
`` tags or block-level elements. The editor strips unsupported elements during content serialization. This is a CKEditor 5 limitation, not a bug in this extension. **Workaround:** Captions wrap naturally based on the figure container width. Since version 13.6.0, the ``
`` element is automatically constrained to the image width via ``max-width``, so captions wrap within the image boundary without additional CSS. See :ref:`examples-image-styles` for details. .. note:: This limitation applies to all CKEditor 5 figcaptions, not just images from this extension. See `CKEditor 5 image captions documentation `__ for details. ---- Related Documentation ===================== **Other Troubleshooting Topics:** * :ref:`troubleshooting-image-reference-validation` - Validate and fix broken image references * :ref:`troubleshooting-installation-issues` - Installation and setup problems * :ref:`troubleshooting-frontend-issues` - Frontend rendering issues * :ref:`troubleshooting-performance-issues` - Performance optimization **Additional Resources:** * :ref:`integration` - Configuration guide * :ref:`ckeditor-plugin-development` - CKEditor plugin architecture * :ref:`integration-configuration-rte-setup` - RTE setup and image selection Getting Help ============ If issues persist after troubleshooting: 1. **Check GitHub Issues:** https://github.com/netresearch/t3x-rte_ckeditor_image/issues 2. **Review Changelog:** Look for breaking changes in CHANGELOG.md 3. **TYPO3 Slack:** Join `#typo3-cms `__ 4. **Stack Overflow:** Tag questions with ``typo3`` and ``ckeditor`` .. important:: When reporting issues, include: * TYPO3 version * Extension version * PHP version * Browser console errors * RTE configuration (sanitized) * Steps to reproduce
