Bug #99278
Updated by Daniel Siepmann over 1 year ago
Opening the Install Tool on a v12 displays a messages:
> The Install Tool is locked
>
> To enable the Install Tool, the file ENABLE_INSTALL_TOOL must be created in the directory typo3conf/. The file must be writable by the web server user. The filename is case-sensitive but the file itself can be empty.
>
> Security note: When you are finished with the Install Tool, you should rename or delete this file. It will automatically be deleted if you log out of the Install Tool or if the file is older than one hour.
But there is no more typo3conf/ within the installation. The code also still points to the folder: https://github.com/TYPO3/typo3/blob/main/typo3/sysext/install/Classes/Service/EnableFileService.php#L30
One can create the folder with file within `public/` but I don't think that's how it should be.
