I increased the memory limit and still the same problem. I am using wootheme’s Canvas theme, a compatible theme. If i switch the theme back to the Buddypress theme, it all works.
You need to install/activate the BP template pack plugin to make WP theme compatible with BuddyPress. I don’t know if the JS conflict has been fixed with Canvas already, but here’s what we tried to work out before https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/woo-canvas-child-theme-customization-and-ajax/
EDIT – at end of that page http://labzip.com/shop/canvas-child-theme/ which claims compat with BP. I would suggest before any purchase that you make sure it’s compatible with latest BP and WP pages.
