Hi Guys,
My new content default page looked like this:

I edited Extensions>MicroTiny>Settings to Allow images.
This added the "tree" icon to the menu bar but when I use the tree icon, and then click the browse icon adjacent to Image URL field I get the following error screen.
Not sure if it makes a difference but pop-ups have been set to "allowed" in browser for the domain.

Any help appreciated.
Cheers,
Gene Stevo.
