I think the problem you told me about “reaching entry process limit” might be the issue am facing
This might be the problem, because after editing for a while is when the error appears.
so how can i sort this issue?
If you don’t have FTP software, you can use File Manager in Cpanel. The Plugin folder should be under “htdocs/wp-content/”
508 Error is Entry Process Limit. That means if you try to refresh the page too many times, or too soon you your account will reach Entry Process Limit and with 24 Hours Account Suspension. So be aware about it.
Some people also benefit from the Heartbeat Control plugin. Normally, WordPress’ admin interface does some background traffic, which can rack up if you spend a lot of time in the editor. Maybe it can help you too?
