Hello @rui-freitas
I hope you’re doing well!
I apologize for the late reply in here. I’ve visited your site to check this issue, but I am afraid it is not online.
Please let us know when your site will be back so we could review this issue.
Was there any plugin/theme update done on a site before the pop-up disappeared? Please see if there is another plugin conflicting with the Hustle. Deactivate all plugins, besides Hustle and see if the pop-up is back.
If it is back this means another plugin conflicting with Hustle, start activating one plugin at a time, until the plugin that causes this is found.
Thank you Frank (@optimizingmatters) for chiming in, we will keep a note of this ??
Let us know how it went!
Kind regards,
Nastia
