410 Gone error after WordPress update
Last night I updated joinordie.com to WP 3.9.1 via the dashboard and today the site gives a 410 Gone error. I'm not certain that the issue is WordPress but it seems likely due to the timing, right?
Gone The requested resource / is no longer available on this server and there is no forwarding address. Please remove all references to this resource.
The site was fine right before the update. It only uses 2 plugins: Disqus and Widget Logic. I doubt they're the issue. What can I do to fix this? I can't get into wp-admin because it's 410 gone too. Should I try to manually reinstall WordPress via FTP? What could cause this error and how do I fix it?
Update: I just noticed that the error occurs on another (non-WP) site for the same FTP user.
Answer
Thanks to Will Thresher I was able to discover the exact problem. In the .htaccess on both those sites there was code for Perishable Press's 2010 user agent blacklist. I removed that code and it worked fine. So the answer is to check .htaccess and remove any problematic rules.
