Layout: Problem with adding region and add Image to region

Hello,

two littel problems:): i would like to create a region, but after clicking on the add region button in an open layout:

there comes a bad link with pointing to “myserver/region/5”.and no new region is added.

The second Problem is, when i would like do add an image to a region and click on the button, nothing happens.

Do you have any idea?

Thanks!
Yours Mark

Ok thanks! I replaced the views “layout-designer-page.twig” and “base.twig” in my theme and no its working. Top!
