Hi, I read this post below in the forum. It looks like the post was from last year. Has this issue been addressed? I too would like to use/see the post carousel when working with a header that I designed in the header builder.
Post Carousel is part of the Standard Header of X and Pro Theme. Using Pro Theme header builder essentially you are creating custom headers. When a custom header is designed using header builder, it will override the default features and functions of standard header that unfortunately includes Pro Carousel.
