The support member is wrong, files _are_ being cleared from cache. Depending on the circumstances new filenames will or will not be created. Also; immediately after clearing AO will automatically warm it’s own cache, and that is what probably leads our support member friend into believing the CSS/JS cache is not cleared. But believe me when I say the support member is wrong ??
(real stubborn guy, that support member, the only thing he _really_ should do, instead of questioning all of this, is just tell the devs to remove that autoptimizeCache::clearall()
-call because the AO-developer says they should not call that function upon every post publish/update because it’s hurting performance significantly!)
