It has not fixed the error messages. Of interest, there is *no* field named custom_avatar_url in the smf_settings table.
There is one called avatar_url
But that didn't fix the error messages either. And the error message is still showing that it is trying to pull the smf_settings table out of the photopost database, not the SMF database:
Content visible to verified customers only.
Until there's a fix on this, I'm totally disabling this line of code. We don't show the avatars anyway.
And I can hardly wait to see the hate-mail from our host about the number of emails this generated.
