Those of you who use the excellent WordPress plugin Bad Behavior, should upgrade to version 2.0.11 straightaway.

This is because the author has recently made some changes to his server which means that BB can get a little ‘over-zealous’ and not only prevent anyone from leaving comments on your blog, but can also prevent you from logging on to your admin panel. Simply visit the authors page to read about it and to download the new version.

Of course if you have been locked out, by this or any other plugin in future, connect to your webhost via FTP, delete the offending plugin and everything should be back to normal.

If you don’t use this plugin, but suffer a lot of comment spam, I strongly recommend it. In the two days I had it turned off while the author fixed the issue, my comment spam reaching Akismet more than doubled. Additionally, if PHP based spambots go a little crazy on your blog, it can cause your webhost to take your site down – BB stops them completely in their tracks.
