Hi,
In Chrome, Firefox and Safari, when I go to the backend Subscribers menu, select one or more subscribers and then click on the button "Subscribe", I get an empty/blank popup window. MS Edge works fine.
Using Joomla versions 3.1.11 and Acymailing Starter version 7.9.6
I saw another post in the forum with the same problem, but with no solution in the thread: https://forum.acymailing.com/d/568-add-to-subscription-is-blank
Could somebody help me with this?
Kind regards,
Cristóbal
