The following error appears at the top and bottom of my wordpress blog:
Deprecated: preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /home//public_html/wp-includes/kses.php on line 1744
The line in question is this:
$content = preg_replace( '/[\x00-\x08\x0B\x0C\x0E-\x1F]/', '', $content );
How can I solve this?
I am just starting at web development, so I couldn't find success trying to change some code in the kses.php file. I managed to find it via file manager (cpanel, etc). I tried reading tutorials related (Youtube video), but it didn´t work out.
