It seems CSS and JS not working on Home page

Dear moderator,

I have released my first website last week and everything seems working fine. Since yesterday everything broke on my home page. All the content is there without styling. I am using beaver theme and Beaver Builder pro version.
Here is my home page link: https://sterlink.de

Your valuable help is much appreciated.

Greetings,

I visited your site and I am not seeing anything broken on the homepage. Is the issue now resolved?

If not, then it could be related to caching.

Dear Danny,
Thank you for your response.
I have completely recreated new home page and it seems working now.

I am having same issue on another page. (sharepointconsult-banner - STERLINK)
I have created a landing page using different rows and modules. After publishing it everything broke. If I open it for edit using Beaver Builder all the content is wrapped inside one row with Text Editor.
