Current Version ON Your Extension Page Says it is 6.11.1 but it’s not. Even when updating via the Bulk Extension Manager since the update showed up, all it does is update and remove the same exact version that was already there.
So, I downloaded a clean copy of the entire X-Theme package, and sure enough, the version uploaded in extensions of from February 6.10.2 not 6.11.1 which is what is should be at this point.
