Deprecated function in PHP 8.1 with WordPress 6.2

[salvoaranzulla]

On WordPress administration with WordPress 6.2, I see 2 deprecated functions:

[07-Apr-2023 12:26:46 UTC] PHP Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /.../wp-includes/functions.php on line 7053

[07-Apr-2023 12:26:46 UTC] PHP Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /.../wp-includes/functions.php on line 2165

@salvoaranzulla Does this error still show up after doing a reinstall of WordPress via updates -> Re-install v6.2 again.

Could you also attach some screenshots where exactly this error is coming up?
Have you any plugins installed? Since, I don't see this error appearing on my 6.2 websites running PHP 8.1

You are right. The error is generated by a plugin. Sorry for my ticket.

@salvoaranzulla hello witch plugin does that to you i have the same problem thanks a lot.

@salvoaranzulla I have the same question as @insecttrojan. Can you remember the plugin causing this? Thanks

I would like to know which function the plugin used incorrectly, especially if it included a wrong type in the add_submenu_page() function.

If you could determine which function or which plugin causes the error, please share the information on #57580. (I am not yet sure about reopening that ticket, but you can comment while it is still closed.)

In my case I debug and was the header-footer-code-manager and the wp-google-places-review-slider
