Comment (by voondist):

 It seems like you're encountering a PHP notice related to an undefined
 offset in the wp_resolve_numeric_slug_conflicts function within WordPress.
 Specifically, the issue occurs when $postname_index is 0.

 To address this and potentially reduce the size of your error logs, you
 can modify the code to handle this scenario more gracefully. Based on your
 description, it sounds like you're considering skipping the problematic
 scenario altogether. Here's a snippet you might add to the if statement at
 line 363:

 php
 Copy code
 if ( 0 === $postname_index ) {
     // Skip processing when $postname_index is 0
     return $slug;
 }
 By adding this condition, you're ensuring that the problematic scenario
 where $postname_index is 0 is skipped, thereby preventing the PHP notice
 from being triggered.

 Remember to thoroughly test your changes to ensure they don't introduce
 any unintended side effects. Additionally, consider the implications of
 skipping this scenario and whether it aligns with the desired behavior of
 your application.
