Debugging a page¶
Click Debug on the Admin Panel bar to show general information about the page.
There are four tabs in the Debug section.
The Events list shows all events that were dispatched while the current page was rendered. A developer can use this list while extending TYPO3 to find out which event to use on any given page.
Click the arrow to expand the details for an event to see basic information about the event’s parameters.
The log tab shows all log entries that were generated during the current request. You can adjust the log levels and grouping in the settings.
Click the cog icon at the top right of the Admin Panel bar to configure the settings.
TYPO3 has a concept of “Page Title Providers”. The section “Page title” displays all registered providers that were checked for the current page. This helps to debug where the currently used page title is coming from.
Displays a list of SQL queries that were generated on the current page and their performance.
Click on a query to open a detail view with the values used for the placeholders.
