I just found this as well. I could trace it to another plugin from the author. WPDash notes, if you have it enabled it in your site it will show the banner at the top with no way to dismiss it!
Other plugins from the author could be involved as well, I have WPS Menu Exporter installed, but not active, so I can’t tell if this one also displays the ad.
In my case, i have WPS Menu Exporter active but i deactivated it and deleted it too
I really hate when these big, obnoxious ads get placed on my Client sites. I found out about it because I received TWO client calls. what a waste of my time. Now, I am implementing strategies to block it across all my managed sites.
Good morning,
Sorry for the inconvenience, I corrected the problem of ads being displayed excessively.
Sincerely.
