.. include:: /Includes.rst.txt ========================== TYPO3 Exception 1301648780 ========================== .. include:: /If-you-encounter-this-exception.rst.txt PageNotFoundException ===================== Wrong Site Configuration ------------------------- In LTS 9 this exception occurs when the rootPageId in the site config (:file:`config/sites/domainname/config.yaml`) does not match the pageId of the page that is set as root page. Wrong preview/extension configuration ------------------------------------- The Exception occurred after updating to 6.2.9. When editing a `tx_cal_event` (:file:`/typo3/alt_doc.php?edit[tx_cal_event][135]=edit`) and using any of the "Save"-Links, the Error "Page Not Found (404) The requested page does not exist!" is shown and nothing is saved. The resulting URL is `/typo3/alt_doc.php?&edit[tx_cal_event][135]=edit&returnUrl=dummy.php` which might hold two hints: dummy.php and the missing key/value in the query string directly after the question mark. **SOLUTION** The solution was, that the SysFolder had a Page TSconfig entry :typoscript:`options.tx_cal_controller.pageIDForPlugin = 419`. The page 419 had been deleted. After removing the option cal worked again. So be sure to check the page TSconfig for wrong entries
