Hello, I have a Pydio 8 installation running in one server and after copying it to another server, the application doesn’t run, the error reported is: ``` [Sun Nov 29 15:27:07.764898 2020] [cgi:error] [pid 45876] [client xxxx:33620] AH01215: PHP Fatal error: Uncaught exception 'Pydio\\Core\\Exception\\PydioException' with message 'Severe error while loading plugins registry : There was an error trying to connect to your database!

After copying it to the new server, I modified the mysql login details in data/plugins/boot.conf/bootstrap.json. I’ve checked that the login credentials are right. I don’t have cache files (\*.ser) in data/cache/ Could anyone give me some advise in order to fix the issue? Thank you very much! ---

Hi, Please make sure you installed php-mysql (php-mysqli) and correct mysqli option in bootstratp.json ---

Hi, I will check it but other php-mysql applications work in the server. I will also try the migration to cells. Thanks. ---

Hi, I’ve tried to install and run cells but I could do that in my shared hosting and also it consumes a lot of memory I don’t have. I checked that I have mysql and mysqli extension activated in PHP and the tight credentials in the bootstrap.json file My previous host uses MySQL 5 and the new one MariaDB 10. Could be something related to that? Any other advise on how to find the issue? Thanks! ---

I tried a fresh installation of pydio 8.2.5 and it works perfectly so I finally “moved” the users and data from the old installation to the new one. ---
