I like the theme but it is BROKEN. The navigation on the side does not work, so I cannot get to settings to change it back. Also, when visiting a page, the top half of the page is just white.
Are there any interface admins in the Snap! wiki? If so, please come to the rescue!
EDIT: It is okay now. I checked my history and found the page.
You could have appended something like ?useskin=vector2022 into the URL. This will temporarily change to a skin that is stable for the time being, then slowly walk to the preferences and change the skin back.
Apologies for the delay. It should be fine now. I had to remove some custom code we added in order to have a header similar to the one on the main Snap! website which appear to have ceased being compatible with the latest updates to Citizen's code.
