First of all, thank you for your quick and kind reply.
Unfortunately, you have to know that you’re dealing with a “noob”. I’m ok with the inspector part but, what am I supposed to do to make these changes effective? I mean – here it is the noob statement – when I refresh the page the value is reverted to the empty “” and the shortcode isn’t working on the page.
Sorry for my complete ignorance, I’m yet a very beginner.
You have my 5 stars anyway because of the plugin itself (the fault here is from ACF Frontend) and because of your support.
Thanks
