The error message is:
Notice: Trying to get property of non-object in /customers/2/d/3/cofindrs.com/httpd.www/wp-content/plugins/buddypress/bp-core/bp-core-filters.php on line 923
This is probably down to a plugin conflict, try deactivating all other plugins to see if the error goes away.
Thanks for your help – it was a GTranslate plugin. I guess this means that I can’t have that plugin activated simultaneously with BP?
You could ask the developer to fix it, but yes until it’s fixed that it’s best not to use it.
@cofindrs,
a php notice is generally harmless and doesn’t compromise the way your site works.
If you deactivate wp_debug, this message won’t show publicly. On a production site, you shouldn’t activate wp_debug anyway.
If you’re sure you isolated the culprit, open a ticket on the plugin support and give any details who can help the author to reproduce the issue and to publish a fix.
If you aren’t a php freak, you cannot do more than wait for a new version, but you can continue to use the bugged version.
