Can't scroll down without login
when I log out the website gets unscrollable again
in inkognito mode everything is fine though
weird
When you visit the website for the first time you will get a pop-up notification about the cookie settings. When you hit 'Options' and after this you hit one of the two buttons, either 'Save & Exit' or 'Accept All', you won't be able to scroll through the website anymore after a refresh. I assume when you log in, the cookies are automatically accepted.
Could you clear the cookies and check if this is the issue?
after I deleted all cookies and accepted them anew it worked
If you can make sense of it, thats fine by me
