Do you have nay plugins other than BuddyPress installed and active?
I have the Next Gen Gallary plugin installed. Is it causing all the problem?
I do not know if the NextGen Gallery plugin modifies the wp_sitemeta table. I suggest that you disable the plugin and see if the issue goes away.
If you are running a newer version of WPMU than is currently supported by NextGen Gallery, you could have issues.
Also, I do know that there are some issues running BP with the NextGen Gallery plugin–with avatar cropping. It’s possible that is could be causing other issues as well. Contact the developers of that plugin and ask for their help and whether or not they plan to support BuddyPress.
Thanks Jeff . I’ve disabled the plugin now. I’ll observe the site for next two weeks. In the mean time, I wish to display slideshow in posts. Any suggestions on how to do that? Any plugin that is known to work well?
The NextGen Gallery plugin is a vary powerful and popular tool for WP bloggers. I suggest contacting the developers and asking them if / when they plan to support BuddyPress. Also, perhaps they will have some insight into this issue.
Whether this plugin is causing your particular issue is yet to be determined.
