Break => Error to access parameters menu

Nextcloud version 13
Php 7.2
shared hosting 1and1 Ionos
mysql 5.5


I installed Nextcloud 13 in shared hosting 1and1 (now ionos). It’s ok, I synchronize my files, calendars, contacts… It’s great…
I have acces to all interfaces but I can’t access to the parameters, error :

I don’t know what to do. Thank you for help me…

why nextcloud 13 and not nextcloud 16?

You should check the server log files to find the root cause of the problem. Additionally you should install a supported Nextcloud release, e.g. 16.0.2, because v13 has already been declare End of life.

It’s when I wanted upgrade nextcloud throught parameters menu than I saw this bug…

you need to be more specific about your distro.
