I upgraded to DNN 6.2.9 from 5.5.1. After the upgrade, I noticed I've been unable to Edit Content (See the link below for a picture).
When the "Edit Content" button is clicked, nothing happens. In addition to this, when I move my mouse away (un-hover) from the action menu, the menu does not fade away. Instead, it stays on the screen with the "display: block" in-line css property.
I have the same problem with trying to edit the site's modules. When I click "Yes" or the "edit icon" to edit a module (in edit mode), nothing happens there either.
Thanks in advance for your help,
P.S. the plan is to upgrade to 7.3 but I'm stuck with 6.2.9 until I can upgrade my .NET Framework from 3.5 to 4.5.
