    Hi there!

    I use WP Debug. I occur with the following warning which appear on three parts of our corporate WP multisite: “Warning: mb_stripos(): Empty delimiter in /var/www/html/wp-content/plugins/fast-velocity-minify/inc/functions.php on line 262”. How to solve this issue and how it may affect to our site?

    WP_DEBUG should be off on production sites for security reasons. Debugging, is for development purposes only.

    A warning is just that. It doesn’t affect your site in any way.
    But you if you don’t want errors to be showing, you should keep debugging disabled.

    In addition, we don’t use mb_stripos on our plugin.
    Perhaps your server is configured in some way, that its forcing it’s use instead of the declared function.
