I upgraded my website to DNN 6.0.1.  I had a problem, see here, but got everything working except the XML module.   I upgraded the XML module to 6.0.1 after upgrading DNN.  Here is the error that I get from the event viewer:

It appears to be an security issue, but everyting else on the website is working fine.

Any help would be appreciated as I do not know the first step in resolving this problem.

Thanks,
Greg

So I think I have figured out the problem.  My production website is using Shared Hosting where IIS6 is locked down to a medium trust.  All of my testing has been done on my personal server with the default or full trust.  On my personal server I changed the web.config file to a medium or full trust and I can reproduce the error. 

So it appears the 6.0.1 XML module is not going to work with Shared Hosting. 

So how can I revert back to the 4.3.5 XML module that works with a medium trust?

Thanks,
Greg

The very best way would be to restore a backup before upgrade!

Other options:
  • Wait for a hot fix release though I cannot promise anything
  • If you are not running DNN6 (*):
    Copy DotNetNuke.Modules.Xml.dll from Xml6.0.0 to your bin (*)
  • If you are running DNN6(*)
    Install XML4.3.5 on a different server, delete bin/DotNetNuke.Modules.Xml.dll and copy all files within desktopmodules/xml and app_code/xml from there to  your server.

* If you need to follow these instructions, it looks like you did not have a working backup to revert the installation. I never tested the downgrade, and I can't guarantee it will work.
I strongly recommend that you test the procedure on a staging system. And please don't do anything without a fresh backup.

You must be aware that a manual downgrade may  result in a working solution, though it is NOT a real downgrade. Chances are high that it will never possible to upgrade again.

I uploaded Xml6.0.2 to codeplex, it should fix the issue within Medium Trust

Use on your own risk, it is not much tested yet. As always, ensure that you have a fresh backup.

OK.  I will install on my development site (which now in configured for a medium trust) and test.

On my production site I noted all of my XML module usage/configuration and then uninstalled the 6.0.1 and installed 4.3.5.  Then I added the XML module back to the pages and everything is working fine.  I should be in good shape to upgrade to the 6.0.2 after testing.

Thanks,
Greg
