footer link issues with diablo fun theme

Hello everyone, so I have had my first oh s**t moment with my website and I have no idea how to fix it.
So Basically I have been adding a product to my shop and trying to adjust shipping classes for this item so it only shows a specific shipping cost....anywho, whilst doing all this something has gone wrong and the basket and checkout pages don't work anymore. There is a red banner at the bottom telling me to "return following links to the footer"

I dont know how they got deleted as I wasn't doing anything in code or adjusting anything to do with the theme. I don't mind them being there as I am using the free version, i just don't know how to fix it and put them back.

It is only on the basket and checkout pages of my website, every other page has the footer links on and works fine.

any help would be amazing as I have been trying to sort this out for hours now and no change.
Thanks
Danni

never mind, managed to sort it. if anyone else has this issue it was a conflict with the advanced flat rate shipping plugin. found it by using process of elimination on all my shop plugins.
Deleted the culprit and all was working as normal again.
