I'm using BP Profile Search on two websites. It works ok on the first, and returns me this fatal error on the second:
Fatal error: Maximum execution time of 30 seconds exceeded in /wp-content/plugins/buddypress/bp-core/bp-core-classes.php on line 522
The main differences between the two websites is that there are 1000 members in the first and 9000 in the second...
Could it be that it doesn't handle that many members?
