TYPO3 Core

After installation or migration in XAMPP an existing or new created folder with upper case letters (for example "Picture") will not be found in the filelist after uploading the project (database dump and files) to the apache server --> the file list runs in an error. Root cause is the casesensitive flag in "sys_file_storage" which is empty, but has to be changed to 1. I run the install tool but I did not find any check or config to change it. The only way to get it running was to set manually casesensitive to 1 in the table "sys_file_storage" with phpmyadmin or to truncate the table.
You can simulate that easily creating the folder "Picture" and empty the variable casesensitive.

I found the possilility to change the setting now, a little bit tricky. I still think that the install tool should check that.

Jürgen, what operating system and which file system are you using?

I use xampp 3.1.0 / windows 7 for testing and apache server (case sensitive) for hosting.

If you move between case sensitive and case insensitive file system you need to change the configuration of the storage manually.
We won't fix issues if you don't set the flag correctly.
On creation of a file storage the state of your filesystem is checked and selected automatically.

Do you wish to have a possibility in the install tool to check the storages system?
