It doesn't work with Buddypress v. 2.3.2.1

Hey there Alberto,

How are you doing today?

This should actually be related to BuddyPress plugin rather then BuddyPress Activity Plus.

I’ve found the solution in one of the other threads, please check it out:

I think the problem might be as in the other thread I’ve just updated. Buddypress have fixed a bug in the core moderation function which means that unless you’ve upped the default number of links, activity updates containing 2 or more links are not added to the activity stream and no error message is given.

By default, links using a thumbnail, videos, or documents will have at least 2 links. This is why clicking ‘no thumbnail’ makes it work again.

Try upping the number of links allowed in Admin > Settings > Discussion. Please note that this number is >= (i.e. if you want to allow 3 links, set the number to 4 etc.)

Hope this helps ??

Cheers,
Bojan
