Bug #85298
Updated by David Bruchmann over 5 years ago
Check for broken extensions complains about system-extensions
complained about lowlevel, fluid, and some others, see attached png file
tested on version 9.3
---
Edit:
In the browser-console I can track this:
1) typo3/install.php?install[controller]=upgrade is called but produces an error
2) The debug-message of the script is:
<pre>
Fatal error: Uncaught TypeError: Argument 1 passed to TYPO3\CMS\Core\Error\DebugExceptionHandler::flattenArgs()
must be of the type array, null given, called in typo3\sysext\core\Classes\Error\DebugExceptionHandler.php on line 397
and defined in typo3\sysext\core\Classes\Error\DebugExceptionHandler.php on line 513
</pre>
Don't know if it's helping much, as it's already about "DebugExceptionHandler" ...
