@nebulon neat, the only issues I couldn't fix and didn't have the time to were the error message in the console like
Mar 24 18:03:56 [Tue Mar 24 17:03:56.699195 2020] [access_compat:error] [pid 132] [client 172.18.0.1:38992] AH01797: client denied by server configuration: /app/code/, referer: https://my.cloudrondomain.com, must be something with my apache config but it was working nonetheless.
Is there a way to enable/disable cloudron "integration" (i.e. apache ldap login) so it's either available to everyone or only cloudron users?
The only thing that worried me a little was the upgrade fom 2.1.0 to 2.2.1, it only showed a blank page afterwards, but I reckon we can figure it out on the next one
