Title: MBString Extension Issue After Plugin Update Last modified: December 16, 2024 --- # MBString Extension Issue After Plugin Update * Resolved [Zmicier](https://wordpress.org/support/users/zmicierzavadski/) * (@zmicierzavadski) * [1 year, 6 months ago](https://wordpress.org/support/topic/mbstring-extension-issue/) * Hello, * I recently received a notification in the plugin stating: _“Your server does not meet the requirements for PDF Invoices & Packing Slips for WooCommerce. Please check the Status page for more information.”_ * After reviewing the status page, I noticed the following: - **MBString Extension**: Required – Yes; Present – 8.2.15 (No. Recommended, will use fallback functions). * However, the MBString extension is enabled on my server, and everything seems configured correctly on Hostinger. Could you please clarify why the plugin still shows a fallback warning and if this could affect the plugin’s performance? * Best regards, Zmicier - This topic was modified 1 year, 6 months ago by [Zmicier](https://wordpress.org/support/users/zmicierzavadski/).

There’s no need to worry about it, as the extension (MBString) is working correctly, and it does not affect the plugin’s performance. * The support team mentioned that they are aware of the issue and are already working on a fix for it in an upcoming update. * So for now, you can safely ignore the message. * Kind regards, Zmicier * [Ruud Baarslag](https://wordpress.org/support/users/ruba1956/) * (@ruba1956) * [1 year, 6 months ago](https://wordpress.org/support/topic/mbstring-extension-issue/#post-18202134) * Hi Zmicier, * Thank you for your answer! * Kindly regards, * Ruud * Plugin Contributor [Mohamad](https://wordpress.org/support/users/mohamadntr/) * (@mohamadntr) * [1 year, 6 months ago](https://wordpress.org/support/topic/mbstring-extension-issue/#post-18203494) * Hi [@zmicierzavadski](https://wordpress.org/support/users/zmicierzavadski/) [@ruba1956](https://wordpress.org/support/users/ruba1956/), * The issue has been fixed in the latest version, which was released today.
