I am using CleanCut 1.2.1 theme for a site.
I need to be able to embed a video on the homepage slider. I am using the Avia Slider. Can Avia Slier be updated to the most recent version in order to embed a video?
If so, where can I find documentation for that?
The slideshow by itself has no update for within the theme. The built in slideshow however already has video support though its a bit limited since it only supports flv and swf files. See slide 3: http://www.kriesi.at/themes/cleancut/
A bit of an aside, the theme has not been updated since 2011 and Kriesi has no plans to do so. The last supported WordPress version for CleanCut was 3.3 so the newer versions of WordPress may have issues with the older theme code.
