Hello guys,

We have this site: online.globalstd.com

When users try to activate their accounts in the activation page with the activation code, is showing warnings after clickin on the activation button:

Warning: unserialize() expects parameter 1 to be string, array given in /home/global74/public_html/cursos/wp-content/plugins/buddypress-notifications-manager/loader.php on line 77

Warning: Cannot modify header information – headers already sent by (output started at /home/global74/public_html/cursos/wp-content/plugins/buddypress-notifications-manager/loader.php:77) in /home/global74/public_html/cursos/wp-includes/pluggable.php on line 1219

I tried to activate users without activation but is not working good, because it ask you for activate your account, or if you log out and then try to log in again it shows a message “error: registered user”, so the users can’t enter to their accounts again and we have to delete them and register again.

What do I have to do? thank you.
