I got mines to work by unchecking:
– Cache requests only for [HOSTNAME]
In Performance > Page Cache
Hey Donncha,
For some reason it magically started to work, what i did was switched it back to dev version then checked make known user anonymous.. and i also did copy the index.html(from staging to production) that was missing in my cache folder for that site, but it wasn’t working until.. a few hours later it somehow just started to work. NO IDEA what fixed it but it’s working now, and that page is also being cached.
I’m also having a similar problem and it’s stuck on loading. but i’m using CF7 2.4.6 I reverted to this version because CF7 3.1.2 doesn’t work with my wordpress 3.3.2. (http://wordpress.org/support/topic/plugin-contact-form-7-no-cf7-pages-will-load-after-312-update-wp-332) Anyone know why it’s stuck on loading/not redirecting? E-mails do get sent. Thanks.
