New description:

 Hey guys, I've noticed that these errors started appearing on my website
 since I've installed PHP 8.0. I've actually upgraded to PHP 8.1, and the
 errors persist.

 Can you help me fix them? I can provide you with access to my site, if
 necessary.

 PHP Error Log:

Comment:

 Hi @brmartinez, welcome back to Trac!

 I believe we're already tracking this issue in #34353 (see the latest
 comments in particular, which reference this notice (in PHP < 8.0)/warning
 (in PHP 8.0+).
