Would you mind sharing your site so that we can see a demo of this theme?

Any idea why “new user hook” is called when a user change his password from front-end ?

Try this: ap_user_link(get_current_user_id(), 'profile');

Fixed.

No I did not removed your question. your question exists here: Why you remove my question? I replied to it. I have already sent link to you, please check if its in junk folder. I will send it again if you did not received.

To fix link issue in TinyMCE, please install Advanced WPLink plugin and disable inline link. This may be a WP bug.
