Remove temporary cache files¶
In typo3temp/Cache/Code/cache_core you will most likely find files
ext_tables_*.php. These files
must be removed as well.
Go to "Important actions" and click "Clear all cache":
This method will remove all files from the folder
Additionally, after an upgrade to a new major version, you should also
delete the other temporary files, which TYPO3 saves in
the Install Tool go to "Clean up" to do so.
