Hello,
when trying to upload a file, e.g. a picture in the administrators logo upload function, the indicator wheel starts spinning endlessly and nothing happens.
I have discovered, that the file arrives in the ../data/Utils_FileUpload directory with a file name like "tmp_(some numbers).png". This shows that the file is uploaded but it is not processed.
For sure it is just a configuration problem, but I don't know what to check. Please help.
I'm running a root server.
OS: ubuntu 16.04.01, GNU/Linux 4.4.9
Apache 2.4.18
MySQL 5.7.15
PHP 7.0.8
