try editting the option in your smf settings again. is the hide email checkbox checked (even though you've already checked it and saved it earlier)? I've found out that when a user tried to change his settings via smf in wrapped mode, the settings dont save properly. You may get a "Settings saved" msg, but nothing was altered in the tables. No idea why though, but the only way it seemed now is to update the settings in smf standalone mode.

I'm having the same problem in RC2... The settings are not saved when editing the profile.

I edit the profile, click "change" and then it redirects back to the original profile page. Checking the profile again shows that the profile options ARE NOT being saved.

They save fine in unwrapped mode... Kinda defeats the purpose though.

Edit: As a temporary workaround, check this code out:

You just have to add extra code for the additional fields.
