If all has been working and now has issues, it’s likely due to server updates to PHP and/or a change to one or more PHP settings.
The following PHP settings are recommended to minimize timeout errors;
max_execution_time = 600
max_input_time = 600
max_input_vars = 4000
memory_limit = 512M
post_max_size = 256M
session.gc_maxlifetime = 1440
