Unable to view/edit Site Settings

Describe the bug

I try to load the Site Settings (/Admin/Site-Settings) and get the following error:

Error: Dell Employee Purchase Programs is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\088cf42c\921e3c76\App_Web_login.ascx.ed3f9c87.0ktnw0oi.0.vb(61):

Change the direct reference to use version 8.0.4.226 (or higher) of DotNetNuke.

Seems like the DLLs might be referencing DNN 8.x? From what I could find, it sounds like support for DNN 7.x hasn't been dropped officially - especially since there isn't a DNN 8.x requirement added in the .dnn file to utilize during install.

Software Versions

• DNN: 07.04.01
• Module: 7.0.0

To Reproduce

Steps to reproduce the behavior:

1. Go to Admin --> Site Settings
2. No settings appear - just the error message above.

Expected behavior

I should be able to edit the site settings
