I ran the upgrade wizard to upgrade my telerik version to 2018.2.620 from the Q2 2016 version. However, after the upgrade none of the grid icons are showing up.
I'm using the bootstrap theme.
In my content folder I have a kendo directory with folders for Bootstrap, fonts, images, textures and the kendo.bootstrap.min.css and kendo.common-bootstrap.min.css files. I've included a screen shot of the folder structure.
The Scripts/kendo directory just has the kendo.all.min.js and kendo.aspnetmvc.min.js files.
I have the following css and script file includes on the page:
<link href="~/Content/jquery-ui-1.11.4.min.css" rel="stylesheet" />
<link href="~/Content/kendo/kendo.common-bootstrap.min.css" rel="stylesheet" />
<link href="~/Content/kendo/kendo.bootstrap.min.css" rel="stylesheet" />
I've confirmed using the dev tools in Chrome and using Fiddler that there are no 404's, all the files are getting loaded into the page correctly.
I'm not using any bundler at all. The page just has a Html.Kendo().Grid defined and practically nothing else. I tried removing everything else on the page but the grid, but that didn't help.
What am I missing?
