Hello. I've been having this error for awhile now, and I've seemed to have tried everything to fix this issue. I have a screenshot pasted below for a reference.
Basically, what it has been giving me, is an identical copy of the registration form. I talked with a tech support representative, and they say it has to do with the CMS. If someone else has been having this error, please let me know if you've found any resolutions to this error.
Thanks,
Alan
