When you try to “Comment” on any activity, you get this page: “http://cureuphoria.com/activity/reply/” and it displays the “Page not found. We’re sorry, but we can’t find the page that you’re looking for. Perhaps searching will help”, with the search form.
I tried to deactivate all the plugins and the problem is still there.
I use a sngle WordPress Version 3.2.1. – Buddypress 1.5.1.with a child theme, with only a few templates changed (header, footer, sidebar), and got a “functions.php” file in the child theme.
The problem is really annoying as nobody can comment on anyone activity.
I recall reading somewhere that one of the plugins you have activated, buddystream, is messing up with activity page. Change to bp-default theme and deactivate buddystream and see if same behavior applies. If you have bp-custom.php in your plugins folder, rename it in the meantime.
I just installed wordpress 3.1 and then I installed buddypress, and the Fishbook theme, nothing else, when I try to post a comment I get the same page not found error, with both the default theme, and the fishbook theme.
