Hello, I am running perfect server 3.2 on ubuntu 20.04 I install 2 nextcloud websites on 2 different servers : - server 1. is related to client0 = admin, - server 2. is related to client1 I had issues with jailkit. So, on that server, installation is 'perfect server without jailkit' On both I installed CollaboraOnLine/RichdocumentsCode (it is an addon), but behavior is different. On server 2, it doesn't work : php-fpm is trying to acces a process outside Openbasedir : /proc/number I dig on CollaboraOnLine/RichdocumentsCode obviously, on server differences also... I want also to dig a little bit on ispconfig side : I wonder what are the differences between a website related to client0 and a website related to client1 ? My initial thought was differences are very small (naming) but may be there are others ?
