Hi,

I have just upgraded from 435 to 451 and cannot load the host settings option. I get the following error:

Error: Host Settings is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: ResX input is not valid. Cannot find valid "resheader" tags for the ResX reader and writer type names. ---> System.Web.HttpParseException: ResX input is not valid.

One thing I have removed from the web.config is the build providers is

    <buildProviders>
        <!-- <remove extension=".resx"/>
        <remove extension=".resources"/>  -->
      </buildProviders>

This is so that the DevExpress reports module works correctly with DNN. This was fine with DNN 435

Is this the cause of the error or any clues as to how to correct this error?

All other options on the site appear to be fine.

Regards

Mike
