Thanks for your forum post, but could you please provide some details about what you did before this error occurred? It would be useful to know if this was an install, upgrade, uninstall, or any other scenario. In order for anyone to help, we'll always need these kinds of details so that we can try to duplicate the behavior.

Yes, I installed the module, used the wizard which created the pages, navigated to the pages to see what they looked like and they all came up with this error. I downloaded the different templates and applied them to no avail. It looked like something was out of sync but I didn't understand enough about changing this.

The website itself has been upgraded in the past, so it's not a clean install.
It was on a pre existing website with a new hch install which installed without errors.

The original website was a dnn 6 version built in 2011 and upgraded to dnn 8.0.4 in 2017.

Thank you for the reply - I hope this is enough
Nina

Here's a copy of the event viewer details - It's not much different but perhaps the extra information might help.

Version 03.02.00 of Hotcakes requires version 05.01.20129.0 of System.Web.Mvc. It's not clear why, but the web.config and/or MVC DLL was not updated during install. It's possible that another module conflict prevented the update.

If you update the assembly binding redirect for the DLL in your web.config, these errors should go away. Example:

[code=markup]


[/code]
