Just upgraded to 1.1 and filling in the custom field on personal details page works fine, but if I have the custom field enabled for registration page, it gives this exact error as in the first post on this thread.
edit: tested now. when registering, it gives the custom_fieldsx xx was not recognised error, but still saves the info entered in the custom field and it shows up correctly.
why it shows the error?
I can hide the error by having the following on extra.css, but to be honest I'd rather have this fixed some other way..?
display: none !important;
