If you install a new theme sometimes you get this error when you try to loginĀ 
Authorization code mismatch. Are you accessing this function correctly? Please go back and try again.

Lets see how to fix it

Admin control panel >> template & style >> tempaltes >> your templates >> portal templates>>member_login

Before this


Add this
<input name="my_post_key" type="hidden" value="{$mybb->post_code}">

Do the same to the following templates
  • portal_welcome_guesttext
  • error_nopermission
  • header_welcomeblock_guest
