Edit Page not loading all the way?

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 Twenty Ten theme to rule out any theme-specific problems?

– resetting the plugins folder by FTP or PhpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.

– increasing the memory available to PHP?

The message shown in relation to a failed update might be worth paying attention to.

The fact it failed to complete, means it did start but never finished, meaning you could have missing or corrupt files. Finish the update, even if it means doing it manually and see if the problem resolves itself.

See.

Oh I got it. Thanks for all your help. It was my Contact Form 7 plugin, don’t know why it randomly decided to not work, but whatever, I’ll get a new plugin lol Thanks

Glad to hear you found the problem. ??
