I'm trying to add an alert for my pet in the training center but I'm brought to a page titled "Alerts!", and all it says is this:

Warning: Cannot modify header information - headers already sent by (output started at /www/subeta.net/include/header.php:145) in /www/subeta.net/include/default.php on line 853

[edit] and this issue somehow caused me to make duplicate threads sorry about that!
