Profile Style MixUp with default & user choice.
 

If you allow profile customization, and you then set the profile yourself, that is what they will see.

Even after disabling profile customization for registered users i still see the same issue.

Yes, I know. I was simply saying that if you use profile customization, you need to fix it the way I said to do so. It looks like you have already clicked on your profile customization button and changed it and clicked on Save as Site Default.

Thanks lynne for pointing me to right direction eventhough i have to do it one by one for all members :( i guess but thanks :)

What do you mean do it one-by-one? Did you, or did you not, go to your own profile, click Customize, change things around and then Save as Site Default?

Well i went into my profile change things around and after doing that i was able to see things that weren't clear before but the above problem is still the same... whenever a use select a different style and when they go to their profile they still see the black theme instead of the selected one.

If you went in as an admin and did profile customization and set it as the Site Default, then you WILL see that profile on all profile pages no matter what the style chooser says. Just as when someone edits their profile and sets it a certain way, it doesn't matter what style is selected, you will see their customized profile.

I did that as admin and saved it as site default now still the problem exists is whenever user change to different style they able to use it but when they go to their profile that still shows them black profile.
If you want i can give u a test user name & password and u can take a look & see wat i am trying to explain :(

Yes, I know - that is how it works if you did it via profile customization. If a profile is saved, and you saved one as site default, then it shows like that no matter what style is selected. Unfortunately, the only way to remove your site default is through the database. What is your experience there?
