No content shown on my website

Hello, I just installed lay theme plus caroussel add-on, erased my old content and started new simultaneously to the getting started video to learn the basics. I have a menu, publish content and everything like in the video but my website is completely white. In the customizer I can see the published content. I use firefox, but the same thing happens in Safari. I also cleared my cache, but no change. I feel like there is one tiny box I didn't check, but can't figure it out myself.
Thanks in advance!

@mariusjopen @arminunruh I forget to send you the link to my website https://www.nilsboeddingmeier.com/ and to tell you that under 'permalinks' 'post name' is already checked.

After updating all plugins, it worked finally.
