On my website made with Joomla Hydrogen theme appears a big blue block under the menu

Hi,
after I have searched for hours, I try to find some help within this forum please.

On my joomle website www.sail-in-greece.net it suddenly started to appear a big blue block under the menu bar. My slideshow and the rest of my page are being pushed down and unvisible at first sight, whic is very confusing. I dont seem to be able to remove it. Anyone has any idea what could be he reason and where I should adjust this?

thank you very much

You have Javascript errors, including from Bootstrap 3.3 - so it is likely you are using extensions incompatible with Joomla 4. And your Admin login page is for Joomla 3 - so you appear to be in the wrong Forum!

Your problem is caused by

The Content Security Policy (CSP) prevents the evaluation of arbitrary strings as JavaScript to make it more difficult for an attacker to inject unathorized code on your site.

First of all I am sorry I posted my request in the wrong forum.. can/should I move it?

Second of all, how can I fix this Java script and Bootstrap 3.3 error?
Can I ask here or should I first move my question to the other forum?

Thank you!
