Forum Problem with styles not changing
 

Hi there,

I have installed a custom style on our forum and changed it to the default in the ACP. All users are able to see the reflected change immediately but one of the Administrators cannot. He sees the login page with the new style, but whenever he logs in the forum reverts back to the default style. He has to manually override this by changing the theme via the style selector. This is obviously very frustrating.

This is happening on a mobile device, using Chrome, viewing the forum in full site mode.

I have tried turning the option for users to be able to manually change themes on and off.
I have tried turning the default mobile style on and off.
I have tried going into the user's account to ensure they are set to view "forum default"

What am I doing wrong? Can someone please help? Whenever I changed the style that one Administrator cannot see the change. Other admins can.

We want to periodically change the forum Style and it be reflected on ALL users. It used to work!
