Hi there,
I think there is a bug with the 'Friends List' and 'Friends Limit' or maybe confusion between the two. My partner, who is a super admin, noticed that when she was on 5 friends and about to approve a 6th one, she got the following error:
"Exceeded Friends Limit
Sorry, but you have already exceeded your friends limit. Please contact the site administrator to upgrade your account."
The thing is that we set the 'Friends List' to 5, and 'Friends Limit' to 100.
