select several files to upload , only one file is uploaded

Hello,

I have a nasty problem: when I select several files to upload them, only one file is uploaded, the rest is ignored (same if I upload a folder, only one file of the folder is uploaded).

I reinstalled and still no solution.

Thank you very much for any help!

Regards,
Fabian
