Firstly I'd like to thank you for making such a great feature. I really want to use it on my customer's site.
I'm having trouble saving display location.
I check the checkbox of Everywhere and save, but the checkbox disappears. The widget does not show anywhere. I try checkboxing all the checkboxes and save, nada.
At first I thought it was my theme, so I tried on 3 different themes, including Twenty Twelve, and all have working sidebar regions. But each time I save, the checkbox I checked becomes empty again.
Is anyone having similar issue? Is there any solution?
Thanks in advance,
