I did switch to gravity forms, then my client hired some idiots while I was ill that replaced it with contact form 7!! I am not happy!
It’s only a problem on one page, and I can’t see what could be causing it at all – but the weirdness in the validation is causing ie7 and 8 ajax validation to fall over. But, only on that one page…
That is pretty annoying, considering they’ll just respawn when the plugin updates!
Did you sort this, gilgimech? I am having the same problem..
