Many of you have been asking about skins. The library that we used before the upgrade was outdated and no longer supported.
We have found a replacement library but with that comes change.
We just launched the lounge skins update. The real change is the old code would allow for a lot of CSS errors. This new library is more strict so your code has to be clean. We have provided a CSS checker for you to run your code through. This will tell you if you have issues with your CSS.
The profile and skin updates are complete.
Make sure your code is clean.
Thanks for your patience!
