Whoaaa, that was a nasty bug 😮
Use: Debian 8.8 & Apache 2.4 & php 7.0:
- Install qdpm via softaculous (or manually, it doesn’t matter)
- Navigate to admin page.
and … BOOM: Internal Server Error.
Messages totally misleading. Directory permissions are okay as is the default .htaccess file. Bug is much deeper.
