No problem. The theme was missing the call for wp_footer, which obviously was/is necessary to run a plugin like WordPress Pop-up. Thanks for your help!
I determined the issue and have corrected it. Thanks for your help!
Which version would you include? I have 1.10.1 and it still doesn’t seem to be working.
I have tried a variety of combinations with none of them working, but this is how it is setup currently: http://cl.ly/image/3Y1z011j382b.
