I have recently installed Moodle for a course we are running and it worked fine with initial registrations. But now with just over 700 registrations even if just about 10 people are online, Moodle is fine, but the course itself is not visible for some (even admin at times). Any ideas on how to fix this?
I do see the following in the error logs:
[Sat May 22 07:15:21 2021] [error] mod_fcgid: can't apply process slot for /services/users/zstorage10p1/engeasy/www/culturallyresponsivepedagogy.net/moodle/theme/styles_debug.php
[Sat May 22 07:19:32 2021] [error] mod_fcgid: error reading data from FastCGI server
So your (shared) hosting plan is too weak for your load. Moodle is not any CMS like Wordpress. Moodle needs much more resources. If you want to know more, check the Hardware and performance forum. Make it a point to read the forum documentation linked to the header text of the forum. In any case, your question is not for the developers.
