“Did you add any functions in theme’s functions.php or excluded some blogs in the directory listing Network Admin > Sites with that plugin?”
No, no functions added, no blogs excluded. I’ve deactived the Blogs Directory plugin, enabled the site tracking component of BP.
I also tried pasting the line
bp_blogs_record_existing_blogs();
into functions.php. No joy. Deactivating and re-activating the BuddyPress plugin sitewide with that line in functions.php also did not fix the problem.
Possibly relevant: the only theme currently enabled on the site is BuddyPress default. There are other themes installed, but not enabled at the moment.
Thanks for responding. I checked 5 affected user blogs, those that don’t show up when I enable the BuddyPress site tracking component.
All five blogs have the privacy set to:
“I would like my site to be visible to everyone, including search engines (like Google, Bing, Technorati) and archivers”
I haven’t checked all 50-odd affected blogs, but that doesn’t seem to the problem.
