Hi Paul, thanks for the FlashChat integrations.
I got a sql-error with this one. Seems that " . $fcprefix . " gets the wrong prefix. It returns '_fc2_connections', while the table is 'flashchat_connections'. Works fine when I change to the correct table name in the product xml.
I installed 4.3.3 on a fresh database, with your integration file and instructions.
Keep up the good work!
