Thanks for your fast reply. Unfortunately, this didn’t do the trick. Maybe more info from my site helps? This is my style.css from shapely-child:

@import url("../shapely-master/style.css");

And my parent-style is called shapley-master and in the folder themes/shapely-master.
In style.css I commented out the @import line. If you uncomment the line, you’ll see that for example the button “Erfahren Sie mehr” on the front page is properly rendered (without round corners).
To resolve the issue please make change in the function my_theme_enqueue_styles as i have described above and then change the following line in the style.css file of your child theme
I have modified the above shared function my_theme_enqueue_styles so please try using that.
If it still doesn’t work for you then would you mind if i log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by checking the option “Set as private reply” when replying to this topic?
