Whenever I am working on my site (editing pages, uploading photos, etc.), I will get this error after maybe 10-20 min of working on pages, which prevents me from being able to do almost anything on my site. I normally wait for the error to “resolve itself”, but the wait time has been getting longer. I’m not sure what I can do to fix this. I’ve ran Wordpress’ Repair Database feature, but the same thing still happens after doing this test. Any ideas on what I can do?
