The Upload Files_WA script does not define the findServerBehaviors function
I installed DFP2 after UE4 was installed. After learning that you can't have both installed I uninstalled DFP2 and UE4 and reinstalled UE4. Now when I load the php page I get the following error: The Upload Files_WA script does not define the findServerBehaviors function.
How do I correct the problem?
