I just switched to NextCloud (which is the best of all what exists on the net)
Anyway, I noticed there are are a lot of errors in my logs. (I must tell you I am on a shared hosting service).
This is the error:
set_time_limit(): Cannot set max execution time limit due to system policy at /customers/f/d/9/openstudio.one/httpd.www/client/files/lib/base.php#648
What can I do?
