Actual Error: Value "png" of type "System.String" could not be converted to type "System.Int32" whcih is expected by property type "umbracoExtension"
Been working on a new site for a week and I find I cannot upload any media at all.
Umbraco version 7.5.3
I did have a bunch of orphaned nodes which I have manually removed, but I think that was just another problem.
If I change the connection string and point to a different DB the Media Upload works fine.
Stumped. Any Ideas
