Somehow EXP was erased from two members

I changed a couple of levels for two members, however, they no longer show all the EXP they earned.  In the backend, it shows the EXP they earned, however, on the profile and EXP it shows as zero.  Anyway to fix this?

You need to explain what EXP is?

Iif you changed the membership level of someone. First, try changing the membership levels back to what they were. If the EXPs return, then you know that your query is looking for a certain membership type. Then search your module that handles the EXPs and search for the term IDLevel. There should be one that is in an sql query. Once you find that, you may need to add

AND `IDLevel` = 'New Membership type you tried'

to the sql query.

Okay.  Thank you for the clarification ProfessorSr.
