Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems?
Thanks Esmi and thanks for your service on this forum. Yes, I mentioned that above. Probably should have used bullets to make post easier to follow. I deactivated then reactivated plugins. I’ll try the default theme test but the site was working fine and then just stopped. The only thing I did was add some images to NextGEN Gallery which had already been in use.
Did you deactivate all of the plugins at the same time?
No, I think just the ones I added that day (woops, that’s right that was the other change I made): wp auto upgrade, wp auto backup and scissors. I can try deactivating all of them.
I just added Dean’s FCKEditor For WordPress; it replaces the default editor. It works well. Is that just a bandaid? Should I continue to troubleshoot the problem?
