Too many pictures in slider after update

thanks for your answer. I cant use only one category for slider – its really impractical..

I am not sure what you meant only one category here so please describe it a bit more in detail.

i already tried the child theme which you create for the other topic. It doesnt work for me and accordingly crashes my complete layout, colours, logo and so on…

Have you tried the child theme colorlib-child-theme-103.zip shared in the following topic?

If yes then tell me how are you using it?

After using the shared child theme you have to reconfigure the theme settings in the customizer and it doesn’t mean crashing.
