Support » Plugin: Regenerate Thumbnails » Warning: preg_match(): Null byte in regex in functions.php on line 5219

  • Hi peeps,

    i had this issue just now after installing and running “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 🙂
