Opposition right notice error on Privacy Policy

Hey,

I’m using Matomo since some months on the website that I create and on my page “Pivacy policy” there is a section called " Right of access, opposition and withdrawal" where I put the code that Matomo give for the right of opposition, it’s a check box.

But when I put the code there are some sentences appearing at the end of the page :
Notice: ob_end_flush(): failed to send buffer of zlib output compression (1) in /home/clients/9d2a6f6915c82ce88b02ad82599abeb6/web/wp-includes/functions.php on line 5275

Notice : ob_end_flush(): failed to send buffer of zlib output compression (1) in /home/clients/9d2a6f6915c82ce88b02ad82599abeb6/web/wp-includes/functions.php on line 5275

Notice : ob_end_flush(): failed to send buffer of zlib output compression (1) in /home/clients/9d2a6f6915c82ce88b02ad82599abeb6/web/wp-content/plugins/really-simple-ssl/class-mixed-content-fixer.php on line 110

And it’s the same on all the website that I create.
Do someone know what’s happening please ?

Here is the link of one of the page doing the same : https://letempledeslouves.com/politique-de-confidentialite/

Thank you for your help !
