Upgraded Umbraco from 4.8.1 to 4.11.10 and now whenever I try to create a new folder in the media section I get this error:

However, if I close the error window - a new folder has been created.
I double-checked the config files, ran another comparison of the 4.11.10 files with the existing instance, checked the bin folder, checked the views folder, cleared cache by changing the number in the clientdependency config --- basically everything I could think of to troubleshoot an upgrade.
Error when creating media folder

Any ideas?

A little help here please?
Figured it out. The media type for "Folder" contained a property that was no longer being used, thus throwing an error.
I removed it an it works just fine now.
is working on a reply...
