Just a heads-up... when I was running BBPress, GravityForms and Attitude theme on my site, they did not play well together.
The Attitude theme doesn't allow the BBPress forum to display very nicely. More importantly, when one clicks on a link to go to a forum, you get an error message:
Warning: Creating default object from empty value in /home/communit/public_html/fern/wp-content/plugins/gravity-forms-addons/gravity-forms-addons.php on line 265
Warning: Cannot modify header information - headers already sent by (output started at /home/communit/public_html/fern/wp-content/plugins/gravity-forms-addons/gravity-forms-addons.php:265) in /home/communit/public_html/fern/wp-includes/pluggable.php on line 899
This does NOT happen when the site is using Twenty Twelve theme. I am going to switch over to that theme for operating reasons for the time being but if you want to "make a date" to see this error in action, drop me a line.
