If we attempt to edit a page by clicking on the pencil icon or the edit page option through the page menu we receive the following error
An error has occurred.
An error occurred when trying to create a controller of type 'ControlBarController'. Make sure that the controller has a parameterless public constructor.

We have attempted to remove all modules referencing version 5.0.0.0 of System.Runtime.CompilerServices.Unsafe.dll and we have attempted editing the web.config of our site to reference version 5.0.0.0 of System.Runtime.CompilerServices.Unsafe.dll after copying version 5.0.0.0 of the System.Runtime.CompilerServices.Unsafe.dll, but the error persists.
We have resterted the site multiple times and cleared the cache. Any help anyone could provide would be greatly appreciated. Thank you.
I had the same error. It turned out to be references from other libraries we created for our modules. Once I changed the references on those projects to make sure they were all referencing versions that are the same as DNN does, then I restored all of the DLLs that come from a base DNN install, then copy in our libraries and references but without replacing any existing files in the DNN bin folder, then everything worked and no more System.Runtime 5.0 errors.
That's fantastic advice... It's important to keep your references, .NET framework, and API endpoints all regularly updated to prevent unforeseen issues in the future. :)
By the way, I just discovered a "hacky" way to get the edit bar when this happens.
That got me back in! :)
