I created an empty folder at /Portals/_default/Skins/myThemeName
Inside, I saved an html file with very simple code inside <body>:
<div id="ContentPane" runat="server"></div>
When I try to apply this theme, Evoq says "No theme files exist in this theme." In an older theming video demonstrating this workflow, the DNN representative first applied a theme then "parsed theme package". I can't get that far. Maybe this workflow no longer works with newer version of Evoq, maybe I need to zip and upload the theme?
