So I tried to install an addon update and now suddenly everytime I log in it just gives me an error with all my accounts. I can't get to the admin panel and my members can't see the board.
The add-on is is probably also included in the database. Deleting the files can then cause additional problems.
If you can't find and change your php version, you can add this line in .htaccess: AddType application/x-lsphp73 .php5 .php4 .php .php3 .php2 .phtml to force php 7.3 or AddType application/x-lsphp70 .php5 .php4 .php .php3 .php2 .phtml to force php 7.0.
