1. Once you subscribe to an alert, when you are in user page and you open "Manage your alerts", the page breaks before loading the footer.
The issue seems to be the url:
<?php echo osc_user_unsubscribe_alert_url(); ?>
The function osc_user_unsubscribe_alert_url() doesn't exist anywhere.
2. After posting comment, there is no success message. User thinks comment was not posted. So they post over and over - spams the moderation queue.
3. In "Publish an ad", if you submit a blank form, it still gets posted (registered user). Needs new validation which won't allow posting without title, description, category.
4. If you click "Contact publisher" > Send while the form is blank, weird behavior. First, email address is appears in red border, and a second later, red border disappears and message "We just sent an email to the seller" appears.
