Refused to display ‘https://www.facebook.com/xti.php?xt=[…]’ in a frame

Hi,
I’m using the facebook code to add my facebook page to my website.
I only get an error in the google chrome console. I tried with edge and I don’t have this error.

I’m trying to figure out which is causes this error.

I receive this error:

Refused to display ‘https://www.facebook.com/xti.php?xt=%5B…%5D’ in a frame because it set ‘X-Frame-Options’ to ‘sameorigin’.

There are alot of characters between []. I’m wondering if facebook sdk can cause that. Anyone want else has already faces this error?

I get this error when I add the facebook page plugin. Everythings works, but I want to know why I get this error.

The error appear when I tabbed out then I come back to the website.

Thanks
