From the looks of it, it's most likely a mod that is calling up field15. Check out your User Profile Fields in the Admin CP and see what is in field15, that will probably point you into the direction of the mod. At least that way you can disable it until you get it sorted.

You have a faulty modification installed.

The actual error is the value missing from the IN(,575).

is there anyway to pin point this error? i undone changes i made and i still get that error but this changes all the time now IN (,575); the number always changes
