Hi... these issues may not be specific to your products, WP or Buddypress, but I thought I'd try to pick your brain.
I had to rebuild a site that uses BusinessBlog on buddypress because any time I click on member profile, it says: "Permission Denied
Not Found / No Access. The page you are looking for either does not exist, or you do not have the permissions to access it."
I thought a fresh install would help. It did on this front but created another problem. site works fine without WWW in the url. When I put WWW, I see blank pages. Also blank pages when I install something like a plugin or update it. I now removed all plugins, except Budypress. Note that I took Business Blog and extended it into multisite.
Any idea on these two issues before I kill them and redo the work.
