strstr() and str_contains() errors

Hi,

Your amazing plugin and its exactly what I was looking for to add my own panels to admin dashboard. Thanks.

However in page: wp-admin/index.php

When the plugin is active I get the following erros:

Deprecated: strstr(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/…/public/wp-includes/functions.php on line 1144

Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/…/public/wp-includes/functions.php on line 1151

Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/…/public/wp-includes/functions.php on line 1154

Deprecated: str_contains(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/…/public/wp-includes/functions.php on line 1161

Deprecated: str_contains(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/…/public/wp-includes/functions.php on line 1164

Page: wp-admin/edit.php?post_type=udb_widgets&page=udb_admin_bar also goes crazy with errors.

I’m running php 8.1. If I change server php to php 7.4 the errors go away.

How can I avoid these errors in php 8.1

Thanks in advance.
