Comment:

 Hi and welcome to WordPress Core Trac!

 The deprecation notice for `null` as the first parameter in `esc_url()`
 has been reported on #61268.

 The theme or plugin that makes that value `null` should be corrected. Your
 directory name includes 'loginpress', so I would deactivate that plugin
 first to see if the notice remains. Or if you have a PHP stack trace (or
 backtrace), that could point to exactly where `esc_url()` is called.
