I have a Joomla 2.5.4 site that I updated from 1.5. Everything works fine and the site has been live for several months. However I just examined the _comprofiler table and all new user registrations appear to have a "NULL" value in every field except for the custom fields that I added myself. This also occurs if I add a user manually through the admin. All users can login and access the website fine, but these NULL values worry me and I'm curious why they appear this way.
The _users table has the correct names and values. I've tried using all the tools for community builder, but none of them seem to fix the problem.
