 Hi peeps,

 i had this issue just now after installing and running a plugin called
 "Regenerate Thumbnails" (https://wordpress.org/plugins/regenerate-
 thumbnails/)

 Warning: preg_match(): Null byte in regex in functions.php on line 5219

 I found that it was a permissions issue!

 Navigated to the \wp-content\uploads folder and set the permissions
 correctly, this seemed to get rid of the error messages at least.

 Hope this helps anyone in a similar situation :)
