I don’t have an Android device, either. But my client does, and he’s seeing black on the screen that’s blocking everything. He can touch-and-drag and see what’s underneath, but as soon as he lets go of his finger, it goes black again.
He had the same problem with a plugin I used for the 21+ age wall. I was able to correct that by going into the plugin’s CSS and changing:
@media (max-width: 500px)
to
@media only screen
and (min-device-width : 320px)
and (max-device-width : 768px)
So now the age wall is viewable, but not the site itself, or the WordPress dashboard. Looking at the Flexform CSS, it’s difficult to decipher what specifically to change.
Thanks for your help.
