Mentor Flexslider Block
To add this block to your content tree you must include "Mentor_Flexslider Block" as an allowed child nodetype of the Blocks Folder document type.
These files are located at:
<link type="text/css" rel="stylesheet" href="/css/Mentor_FlexsliderBlock.css"/>
If you have not appended this code to a file already included in WebBlocksBackendScriptIncludes.cshtml then you must include this file in your WebBlocksBackendScriptIncludes.cshtml to enable your block to render correctly in the back-end.
WebBlocksBackendScriptIncludes.cshtml can be found in the scripting files folder in the developer section of Umbraco
