Hi , i am getting these types of errors after i upgraded from version 7.1.2 to 7.4.1. before this i did several upgrades (4.7.2>4.11.8>6.0.5>7.1.2) and everythigs seems to be working fine but now each and every macro script fails to load . Is this due to inclusion of Partial View Macro Scripts because now i cant see the scripts folder under Developer section .(which had all the cshtml files including BrowserTitle.cshtml).

in the stack trace i get this if i set ?umbDebugShowTrace=true.

Error Loading Razor Script (file: Browser Title) c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\26676eb7\92c7e946\App_Web_browsertitle.cshtml.70df5e80.vk8-jzxe.0.cs(24): error CS0234: The type or namespace name 'Helpers' does not exist in the namespace 'Microsoft.Web' (are you missing an assembly reference?)    at System.Web.Compilation.AssemblyBuilder.Compile()

Please suggest me that can i correct these errors by any means.

if not then can i use PartialViewMacroScripts to fix this

Last and Least priority , do i need to build my site from scratch to tackle this.

Thanks
