Almost any application destabilizes the server

installation
#1

Hello

I installed Nextcloud 13.0.1 in a personal hosting in OVH. I can see PDF files in nextcloud without problems but when trying to activate the gallery app it tells me that this application destabilizes the server, the same when trying to activate any other app. Where can I see the logs or get more information?

Thank you

locate nextcloud.log

Is usually located in the Nextcloud data folder.
