We are going through the process of upgrading to 9.3.1.

All our sites have modified Persona Bar and Edit Bar CSS files.

These are being overridden in the upgrade from the following zips in the Install/Module folder:

Dnn.EditBar.UI_02.00.00_Install

Dnn.PersonaBar.UI_02.00.00_Install

We have attempted to take the install files, unzip them, make our custom changes and then zip the package back up again however when we run the upgrade it seems to detect that the files have been modified and errors on the install of the Edit Bar zip package:

[PathNotFoundException: The system cannot find the file specified.]

   System.Web.UI.Control.LoadRecursive() +68
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3785

Has anyone any ideas how we could overcome this?

Thanks,
