That table name looks wrong (based on the table name from the Simple Online List you posted in the other topic). What version of bbPress are you using and how are you getting the avatars to show? Plugin?
Looks like monstet5_bbp01 is the database name, and bb_ is the table prefix, and online is the table name created by the Simple Online List?
If that’s the case there, how do you have an options table here with no table prefix, just a database name?
Unless you used bbp01. as your table prefix instead of bbp01_?
