I just installed the WP Mingle Forum into my site. The theme came with a custom skin to match the site and it looks great.
The issue is after the first post I received this error:
"Warning: Missing argument 2 for wpdb::prepare(), called in /home/bethesda/public_html/whatisthaifood.com/wp-content/plugins/mingle-forum/wpf.class.php on line 405 and defined in /home/bethesda/public_html/whatisthaifood.com/wp-includes/wp-db.php on line 990"
You can view the forum here - Forum
Any suggestions on how to fix this would be greatly appreciated.
