I really like the plugin, and soon I want to go premium. A few days ago, it stopped working and then it was activated again. But now it gives this error, which I think is just a matter of validating the code correctly.
Uncaught ReferenceError: wpColorPickerL10n is not defined
Could you take a look, to repair it in the FREE version of this plugin? …
