Have you tried:
– 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?

esmi — thanks for the suggestions. Will be trying them as time permits and will report back if I come up with a diagnosis, in case anyone else has this problem.

Well, nothing is working so far. I have done a complete manual upgrade (including wp-admin and wp-includes) to 3.0 but certain plugins are still not appearing.
Come to think of it, the “missing” plugins are ones that I have tried to auto-update.
When I try to update a plugin I am asked from my ftp credentials, which I provide. But the response is an error.
And then when I try to delete a plugin, I am also asked from my ftp creds and get an error, like this:
“Plugin could not be deleted due to an error: Could not fully remove the plugin(s) cforms/cforms.php.”
In fact, none of the files for the ‘removed’ plugin appear to have been deleted. So I have numerous plugins that are still on my server but not in my Dashboard.
Uploading a fresh version of the plugin does not fix this.
Any ideas much appreciated…Stephen
Just to clarify…I have successfully upgraded to WordPress 3.0 and Thesis Theme 1.7 (on cobbsblog.com/blog). Switching themes and ‘resetting’ plugins has not solved the problem. My blog is “up” but I am missing some functionality from the ‘lost’ plugings, notably Akismet for spam protection (I canNOT believe the stupid stuff these WordPress spammers try–they seriously need to get a life).
