 * This plugin was working a few days ago, when you updated to 3.8 it caused a critical
   error on the site. We rolled back the plugin to try and operate on a previous
   version and now we are receiving a
 * _“WooCommerce Square requires the **mbstring** PHP extension to function. Contact
   your host or server administrator to install and configure the missing extension.”_
 * Error message. I confirmed that the mbstring extension is on an activated in 
   the Cpanel and contacted our hosting provider to confirm that it is active and
   working. Please advise.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-doesnt-recognize-mbstring-php-extension%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello,
 * I understand you are receiving this error: `WooCommerce Square requires the mbstring
   PHP extension to function. Contact your host or server administrator to install
   and configure the missing extension`
 * The first step that I recommend, is to contact your web host and ask them to 
   enable PHP mbstring extension. A way to manually enable the extension is explained
   here:

 * Hello [@pmcmg](https://wordpress.org/support/users/pmcmg/),
   Could you please 
   share a copy of your site’s System Status Report as well as a screenshot of the
   error? You can find it via WooCommerce > Status. Select “Get system report” and
   then “Copy for support”.  Once you’ve done that, paste it here in your response.
   Look forward to hearing back from you.
