I received an email today from a user who couldn’t post a comment because of issues with the ‘did you pass math’ plugin I was using to avoid spam. EDIT: turns out this wasn’t the problem, so I’ve turned it back on. The problem seemed to be the hashcash plugin when using a proxy site to view the page. I have since deactivated the plugin, and hopefully these issues should be resolved. Sorry to anyone who was having problems with this.
If problems persist or if there are any other issues that are evident, please feel free to contact admin here or by leaving a comment.
