Hi,

 I am new to SharePoint and I have created a workflow using VS2013. I deployed the wsp file using powershell to our SharePoint site. Enabled the feature from Settings->Site Settings->Manage Site Feature. The workflow is associated with a list on the site but it is not working. I checked the List workflow setting, but the said workflow is not selected under "Select a workflow template:". I then tried to add the workflow to the list and got below error. I am using SharePoint Server 2013, VS 2013 Professional, Windows PowerShell_ISE and Windows server 2012.

Server Error in '/' Application.
