I would love for this plug in to work, but instead it says this:

Your Gifts

Fatal error: Call to undefined function bp_has_activities() in /home/content/j/g/o/jgomula1/html/play/wp-content/plugins/buddypress-gifts/includes/templates/gifts/screen.php on line 128

And my nav. bar at the top disappears ??

All updated plugins and newest wordpress version.

Please help, I just installed a fresh new WordPress with no content yet, and then upgraded. I can’t change the theme, despite having uploaded 2.2.1 ready themes into the wp-content theme directory – the presentation tab just doesn’t see any themes including the default and classic ones. Instead I get this across the top of the page, and several others in the admin section.

Warning: array_keys(): The first argument should be an array in /home/liquidne/public_html/stuff/wp-includes/theme.php on line 276

It looked like someone had a similar problem and deleted the classic and default themes? I tried this and got a white, blank page, so I put the default folder back. Is there somewhere I can tell it to go use a different theme?

Thanks for any help, sorry if this is in the wrong area.
