I figured out the problem was because I was using the file based caching that the BP developers recommended here: https://codex.buddypress.org/getting-started/improving-performance/. They might want to rethink recommending something that creates such a big problem! Unless you are going to turn off private messaging, you can’t use that. I’ve gone back to WP-Super Cache (with caching turned off for logged in users) and that seems to work OK.
Well, it looks like messaging and mentions default to the user who made the most recent blog post unless you have just visited other user’s profiles in which case it changes to the previous user you visited, not the one whose page you are on. I’ve deactivated all the plugins I installed recently and that doesn’t change anything.
Ok, I think I figured out that the user that mentions and private messages gets stuck on is the the user who wrote the most recent blog post. I checked in multiple browsers and they were all stuck on that user and then when another user submitted a new blog post, they got stuck on that user.
I’m pretty sure this is related to the problem I’m having that I posted here: https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/possible-bug-private-messages-being-sent-to-multiple-users/. For me it’s not stuck on one specific user, but it gets stuck on the user whose profile you just visited. I just installed BP a few weeks ago on a brand new installation of WP 2.9.2, so I have no way of rolling back to a previous version of the database. Is there any other possible solution to this problem? My site now has 500 registered users and it’s becoming a very big issue and I don’t know what to do about it.
I have this same question but that thread is about something that’s a lot more complicated than I want. Basically I have a WP site that has a large community. I want to add separate subdomain that has it’s own WP install with buddypress and I want people to be able to log into both sites with the same info.
At the top of that thread someone said just to assign custom user and user_meta tables. I’ve already tried that and when I try to log into the subdomain with a root site username, I get a message that says “Cheatin’ eh?” or “You don’t have permission to do that.” So what am I doing wrong? Does the subdomain need to be WPMU instead of regular WP?
