I installed the Telerik controls and they work in the layout.master, but I can't get them to load in a user control.
I created a user control and added it to the feature installation & configurations section. Adding the user control to a page works, and I can see asp controls like a button and text box. When I add a Telerik control to the user control, I get this error:
2020-03-23 12:39:23,642 ERROR 127.0.0.1 - en-US - /telerik-test - mojoPortal.Web.UI.CmsPage - failed to load control controls/mycontrols/usercontroltest.ascx

Why would a RadButton work in the layout.master but not a user control?
Also, I tried replacing asp:ScriptManager with telerik:RadScriptManager. Everything seems to work except that the administration panel on the left side of the page won't open.
I'm using the deployment files, not the source code.
Thanks for any help!!!
