# Warnings in PHP error_log

 * Hello John,
 * I previously wrote about a problem that I’m seeing on my site here [https://wordpress.org/support/topic/php-warning-in-error_log-2/](https://wordpress.org/support/topic/php-warning-in-error_log-2/)
   and by accident, I just stumbled upon something that might be the explanation(
   the old topic is closed, otherwise I would reply there).
 * It appears that this is a not-too uncommon problem with “virtual” pages in WordPress.
   I happen to use the “MailPoet” plugin, and its subscription management/confirmation
   pages happen to be “virtual” (meaning that they are created “on the fly”, as 
   best as I can explain it as a layperson/non developer).
 * I found these two topics. Maybe this is something that would explain what I’m
   seeing? 1. [https://wordpress.org/support/topic/fake-page-doesnt-work-with-wp-6-1/](https://wordpress.org/support/topic/fake-page-doesnt-work-with-wp-6-1/)
   and 2. [https://wordpress.org/support/topic/virtual-urls-php-8-null-issues/](https://wordpress.org/support/topic/virtual-urls-php-8-null-issues/)
 * I know that these are just PHP “warnings” but since my error_log keeps growing
   and growing I have to remember to zap it every once in a while… 🙂
 * Thank you very much,
   Alex.

 * Interesting, ultimately, it still sounds like something (MailPoet in this case)
   is breaking the WordPress API. That said, the function that gets tripped up here
   is slated to get refactored soonish (next major release), in the meantime, a 
   check is being added to prevent the warning.
 * I’m tracking this in the following github issue: [https://github.com/mtekk/Breadcrumb-NavXT/issues/302](https://github.com/mtekk/Breadcrumb-NavXT/issues/302)
