SymptomsI had a problem with the player activity and at first I did not understand why. I went to look and found out that even though the table was created by the correct sql accompanied with the plugin there was a problem with the Collation of the fields within the table!
You wont see anything on your stats page but if you do an
echo $query;
inside the inc_activitygraph.php and then execute that query directly on your b3 database you will see:
#1267 - Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='
SolutionChange the fields collation to latin1_general_ci
