Markis,

I had the same problem you did, and these other suggestions were only moderately helpful. The only thing I found that helped is a plugin called ‘Stop Forum Spammer Registration’. Install that and get it configured and you shouldn’t have many more problems. You will have your hands full deleting the existing accounts and pending comments.

It’s either a permission issue, or the problem I found with extra directories: https://www.jerry-bell.com/fix-for-wordpress-could-not-remove-the-old-plugin-error/

There is one more possible cause of this problem, as I found out. See this for details: https://www.jerry-bell.com/fix-for-wordpress-could-not-remove-the-old-plugin-error/

I have had this problem for a while. I took some time and tracked down the problem and a fix. I have a write up here: https://www.jerry-bell.com/fix-for-wordpress-could-not-remove-the-old-plugin-error/

I hope that fixes it for you as well.

Aaron,

I know this is only 9 months late, but I have an upgrade script here: https://www.jerry-bell.com/2008/04/29/wordpress-backup-script/

I do not have a way to automatically deactivate and reactivate plugins, though. There is a function called deactivate_all_plugins() in the file wp-admin/includes/plugin.php. To perform the automatic deactivation, we would have to unroll all of the things that are done by the function. I am hesitant to run off and do that, as the intricacies of the function may change from version to version. What is really needed is an API that can be called from a command line to perform such a deactivation.
