I recently upgraded to the latest versions of WP/BP from BP 1.2.6 and WP 3.0.3 and since then visitors can not sign-up to the site on IE. I had this problem before and fixed it, but I can't for the life of me remember how. I'm guessing I must've changed some core BP files to fix it and the update has simply overwritten the fix.
Web page error details as follows:

The site is currently live and being promoted heavily so any help in resolving the issue would be massively appreciated.
