Double check that:
- the database still has the information for those fields in the Profiles table.
- any predefined values you created are still there.
- the profile fields are still linked to the predefined values.
- the strings and keys are still within your language settings.

If the answer is yes to all of those then it could be a need to recompile your language files, your modules too. Then it wouldn't hurt to clear the cache.

If you can clear the cache from the admin then see more great but if you have the same problem as I did and it won't let you do it then you may have to do it manually via FTP or Cpanel file manager. If that's the case then make sure you do not delete the .htaccess files.


Hope this works. It did for me.
