Any ideas on this please? I would love to use this plugin for my community. Thanks.
Delete and reinstall (or re-upload) the plugin
Just installed the latest version today & got the same result. I don’t imagine reinstalling is going to help.
Any suggestions? Thanks!
Same issue here. I’m using:
WordPress 3.2.1
BuddyPress 1.5.1
I also have the following plugins installed:
Achievements
Akismet
BP Profile Search
BuddyPress Moderation
BuddyPress Profile Privacy
BuddyStream Premium
Google Analyticator
Hit Sniffer Live Blog Analytics
Private BuddyPress
Quantcast Quantifier
Rank Tracker
Welcome Pack
WPMU Super Captcha
… just in case there’s a potential plugin conflict.
Bump: The plugin does not have a valid header.
WP 3.2.1
BP 1.5.1
I tried erasing and reinstalling and downloading it from the WP site instead of this one. Same result 
Same problem here. The installation guide suggests recognises there is a problem. I tried activating it on the BP blog only without success.
Upload the directory ‘/invite-anyone/’ to your WP plugins directory and activate from the Dashboard of the main blog. Some users have reported problems when activating the plugin sitewide, so consider activating it on the BP blog only.
