Empty alert message TYPO3 Backend when edit filemount (sys_filemounts)

Today, I’ve made a Core-Update from TYPO3 7.6.9to TYPO3 7.6.14(latest 12/2016) on a Windows Server IIS. There were some database changes, mainly sys_file_metadata?!

Now it’s impossible to add a new file mount. I’ve already 20 different file mounts (sys_filemounts) before update, everything works fine. Now I can't select the folder, see image

I wrote the path into the database, but that also won’t work. Only the empty error alert box from TYPO3?! What can I do?

EDIT: The filemount works. I’ve test it with an editor. So maybe it’s a bug :TYPO3 7.6.14? What do you think?

Screenshot from database compare .. do I sth. wrong? I clicked execute …

Solution

Happy Holidays!

There were some files with special characters like ‘ä ü ö’ etc. in fileadmin/user_upload/.... Some of the Editors upload these files via FTP, not via TYPO3-Filelist. Damn ;)

TYPO3 CMS upload change Wrong FIle_2ä.pdf to wrong-file_2ae.pdf automatically - FTP won't.

No bug!
