As described in the mail - it's admin access. The error appears when you hit My Profile from the navbar or when you hit any ad /there are 3 test ads currently/. Error message:
Query: SELECT value FROM smf_settings WHERE variable='custom_avatar_url'
Result: Table 'kupuvaln_p.smf_settings' doesn't exist
Database handle: Resource id #5
So, nobody would access anybody's profile or any ad. I think PPC is looking for member's avatar in the wrong database. There is a table smf_settings but its not in that kupuvaln_p (PPC database), its in kupuvaln_smf1 (SMF forum's database)... Is that causing the error?
Plus, I couldn't find a variable 'custom_avatar_url' in the table smf_settings...
