Hi tuxlog,
I figured out the issue. It was not with the plugin at all. For some reason posting two URLs in group activity was failing too. The offending character being “:” sign. I did a little bit of research and found that the RegEx used in moderating user input (for subscribers) were limiting the amount of URLs I added and for some reason was also limiting the smilies too. So I got into the database and increased the amount from 2 to 5 and it worked.
I am using the up-to-date version of buddypress, bbpress, wordpress and wp-monalisa.
Thanks.
