Hello Sky,
thanks for your fast response. I have tried your tipps.
1. Switching to Twenty Seventeen
Looks OK and Clean.
2. Switching to Default Enfold Theme
Same Blank Page
I added your CSS-Code in Enfold Quick-CSS. No effect.
In style.css. No effect.
BUT
If i deactivate the PRO Version of The Events Calendar, it looks fine.
You can take a look again. The PRO Version is still deactivated.
But wheres the difference ?
Thanks
Dirk
