I'm hoping to find out if someone else has experienced this. I created a wiki, worked as expected in IE 7 and Firefox.
I setup a custom domain name for it. If I use that custom domain name in Firefox, I can log in no problems. As expected, I can still use the wikidot.com domain and log in fine.
But, if I use the custom domain name in IE 7, I cannot log in. The message (in a Javascript alert) is "Error processing the request. You have no valid security token which is required to prevent identity theft. Please enable cookies in your browser if you have this option disabled and reload the page."
Now if I use the wikidot.dom domain in IE 7, everything works perfect.
I even tried putting the custom domain into IE's "Trusted Sites" zone but it didn't have an effect.
Any ideas?
