Important information regarding Style Variables (stylevars) and the Style Generator.
 

Currently work is ongoing with the features of the Style Variables and the Style Generator. The relevant JIRAs are here:

http://tracker.vbulletin.com/browse/VBV-3175
http://tracker.vbulletin.com/browse/VBV-5054

These two issues could have significant impacts on your custom styles and template edits. They may require that you re-apply any customizations. As we have more information, we'll post it here. These changes are being made in the current sprint so could appear in Beta 26 or Beta 27 depending on whether any other issues are uncovered and whether they pass QA or not. We are sorry for any inconvenience this may cause but hope that styling your forums is more straightforward in the future.
