Addon enabled but did not show up on create discussion page.

This addon used to work on vanilla version 2.1.13p1 until after upgrade to 2.2. It enabled on dashboard but did not appear on create discussion page. The default.php code for the addon is pasted below. Please can someone fix this addon, if possible let the addon show disccussion title, body, pictures etc on the email.

Any help please.
Tested on 2.2 and i have no problem with it.

Pleas look if maybe some css style puts the element on display: none
Which theme are you using?
@jackmaessen - thank you for your comment. Please what EmailDiscussion version do you use? Mine is version 0.2 as shown on the screenshot but there is only versio 0.1 on Vanilla addon section. Should I downgrade to version 0.1? I use custom theme cloned from default theme,. EmailDiscussion used to work on my vanilla version 2.1.13p1 but stopped after upgrade to 2.2.
I tested 0.1 and 0.2 version and both are working fine.
You should enable Baseline theme (default theme of Vanilla) and disable all other plugins and see if it works correctly
@jackmaessen - You are right. I had CSS hiding "I agree to the terms of service" and "Remember me on this computer" on the registration page which unfortunately affected the "post a discussion page" too.
