I would try activating default Buddypress theme and see if the issue still occurs so that you can be sure it is not an issue with your theme…
I’m using the default BuddyPress theme…I’ve just restyled the header.
Hey benny148148, followed you here from the “other” forum;)
Here’s the thread I was referencing earlier regarding this same issue on my install (all default)… https://buddypress.org/forums/topic.php?id=1315
However, at the end of the day, there is no solution. One of the BP gurus here, Burt Adsit, was helping me troubleshoot and referenced a possible fix, but didn’t know if it was to be put in trac as a bug fix. I’ve messaged him through my BP install, but haven’t heard back.
I checked trac and didn’t see any reference to this issue. Hopefully other will chime in with a fix.
you ought to paste here the code you’ve changed..
Are you using rc or svn?
Don’t know about benny148148, but I am using RC-1 with NO code changes.
I had this problem too, I found that it was a conflict with some of my plugins.
First, take out any plugins in /mu-plugins and try to activate the email again.
I found that wp-super-cache was causing some conflict in my blog, I took it out and it works perfectly now.
Then, if your activation works, place the buddypress plugins back in /mu-plugins and try to activate.
If these work, then one by one add the plugins that you had until you find the one that broke it.
That’s what I had to do and now my site works fine.
hmmmm…I’m not using any other plugins other than buddypress and Dynamic Content Gallery in the regular plugins folder. This wasn’t an issue a few days ago, but suddenly it stopped working, and I haven’t done anything to the core.
I’m using the latest trunk version, so it’s not a bug with RC-1.
The weirdest thing about it is if I add a subdomain to the activation email…ie. community.domain.com/wp-activate.php?123456789, the domain suddenly becomes activated, and the password is given. Can’t figure out why adding the subdomain to the URL would work, but I just tested it for the heck of it and it actually worked! Now I’m even more confused…maybe I’ll just hack the core and make it send emails out with the subdomain in the link 
… but really, I’d love to know why that is happening…I know hacking the core isn’t the best idea 
To see what exactly I’m talking about…check out the two links below and take a look at the URL in each one…both have the exact same activation keys…but only the one with the “community” subdomain shows up correctly:
Activation WITH “community” subdomain:
http://tinyurl.com/bljm5s
Activation without “community” subdomain:
http://tinyurl.com/be7m6e
Check your error logs, the one without the subdomain is causing a fatal error.
I don’t have any errors in my error log for the past two days. Is there maybe an issue with me using the BuddyPress home theme in a subdomain? My root’s theme doesn’t have any customizations for BuddyPress (although I did add register.php, activate.php, plugin-template.php and sidebar-template.php to the themes directory).
It seems like everything works when I “add” the community subdomain to the links…but I don’t know why.
Edit: This even includes the register link…when I try domain.com/register, it redirects to a login screen, but when I use community.domain.com/register, it works perfectly! What is the secret magical power of the community subdomain?!
Hi, I have exactly the same problem and nobody seems able to help me . Did you find a solution for this, Benny148148?
Thanks in advance
This is a fatal error, there will definitely be something in your php error logs. Or turn on screen error reporting on.
Hi, thanks for your answer.
The error I get lately on the log is this:
PHP Warning: html_entity_decode() expects parameter 2 to be long, string given in /home/freak/public_html/wp-content/mu-plugins/bp-activity/bp-activity-templatetags.php on line 240
Any clue about that?
