In Acrobat XI, I've got my "Manage Internet Access" set to "Allow PDF files to access all web sites." Despite this, when I try to run a custom plugin that accesses a web service. I'm getting the following error:
Error! Your Adobe settings do not allow web service calls. You can change this in Edit -> Preferences -> Trust Manager -> Change Settings
I tried adding my hostname to Enhanced Security, but it didn't help. It worked when I turned off enhanced security.
