Users cannot create posts

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?

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

– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress?

– increasing the available memory?

Hi esmi,

Thanks for your reply. I had not yet tried those things because we have three web servers that run WordPress. All are set up identically. I was able to install WordPress 3.0 with no difficulties on our development server. I will give those things a try and see what happens.

I tried all of those items listed and the problem remains.

If this is specific to just 1 upgraded install, then it could be that there was a problem when the database was upgraded – possibly in the wp_usermeta table. Do you have a pre-upgrade database backup?

I do. I compared the two wp_usermeta tables and the only difference was a user that was in one database and not the other. There were a few more in the wp_options tables (about 60ish) but none jumped out at me. Is there something I should be looking for?

Does anybody have any ideas? This is kind of a big deal.

Any updates to this? I’m having the same issue.
