Yep, my problem still existed but as I didn’t receive any more answers I changed to another plugin which works just fine.

Thank you anyway for your reply.

Hey,
I activated wp_debug and just got this warning:

Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /data/web/e95326/html/wp-content/plugins/revslider/includes/operations.class.php on line 2858

I deactivated the Rev Slider Plugin and the warning disappeared (apparently) but adding/editing new galleries are still not possible.

Yes I do!
So sorry for the late reply.
