[Help] Php error

[nooberalol]

Any Idea how to fix this error? Some times it appears and some times it doesnt, it is very random.
Im using MuOnlineWebs v.2.2.0

You can check the database or the files indicated on the screenshot it self what makes the issue occur if you know how to read php codes. It seems the mLevel is the culprit.

Maybe I can help you on the future, I am doing a service for a donation. If you wanted too. Thanks
