Nextcloud Uploadsize only max 9.9 kbyte

Nextcloud version: 12
Operating system and version: Ubuntu 14.04
Apache or nginx version : Apache/2.4.7
PHP version: PHP 7.0.19
I’m using Plesk 12.5

The issue you are facing:
Files can only be uploaded if they’re smaller then 10kbyte (9.9kB is working)
Everything >=10kByte will be canceled with a “Internal Server Error” Message.

Can you reliably replicate it? (If so, please outline steps):
This happens with every file with desktop client and webclient.
