To put it simply, the free version doesnt work.
I am unable to SAVE or PREVIEW the Optin Popup 1 despite checking everything such as headers etc.
I'm able to turn the plugin on, but thats it. When I try to create a new popup, the green save/preview buttons dont respond. Also when selecting Mailchimp in the Email Marketing Form option, it says Please Wait... and nothing else.
Certainly not going to pay for something I cant see working.
