People who got an error 403 while leaving comments – A BIG SORRY! It turned out to be a setting on my new anti-spam plugin that needed tweaking.
Thanks for your patience, and thanks goes to PR for the heads up.
For the troubleshooters, this is for:
WordPress plugin: Bad Behaviour
Error message: Error 403, with error message relating to “You submitted a form to the site which originated from a different web site”
Why: URL rewrite was done. The blog had an post URL format of
p?=12345, which was rewritten to an SEO-friendly URL format of
YYYY/MM/DD/post-name/ to make things easier for another plugin.
Fix: you need to enable this option in settings:
Allow form postings from other web sites (required for OpenID; increases spam received)
