As you know, the profiles look like junk in customised styles, but I have found out the very simple reason that is and how it can be fixed. If you want your profiles usable in the custom styles for your board, follow these steps:
- Go to Styles and Templates and then Style Manager
- Now go to the Additional CSS Definitions
- Take out your custom code, and keep it somewhere safe for now.
- Click the box to revert this CSS
- Save the changes
- Now, go back and add in your custom CSS underneath. You should realise that the box content has changed a bit.
This then makes your profiles work perfectly well on custom styles. And if you backed up the custom stuff, it should also keep your CSS changes you added to the styles. vBulletin, when you upgraded just forgot to ask you to revert this and hence killed custom styles accidentally. This simply fixes it.
