installes a fresh one some time ago, its up to date on 5.8 now

The plugin is freshly downloaded, and no, we own our own server

We had issues before with a theme where we had to give in ftp credentials, but then it worked.
4 – The error message, is it on activation (preventing actual activation)? Could you share a screenshot?
