i upgraded to 2.2 from v2.1.8 Patch 2 and the twhole website is messed up and design layout is completely broken
I also tried to import the theme back to my styles but that didnt work
If using a third party theme... check to see if they have updated it to 2.2 compatibility... there were changes that were made, and updating the style is usually part/parcel when you update XF.
