# PHP error in testing

 *  Resolved [MBWD](https://wordpress.org/support/users/mbwd/)

 * [10 years, 11 months ago](https://wordpress.org/support/topic/php-error-in-testing/)
 * Receiving this error after successfully completing a test transaction:
 * `Fatal error: Call to undefined function Stripe\Util\mb_detect_encoding() in /
   home/koolestate/public_html/wp-content/plugins/stripe/libraries/stripe-php/lib/
   Util/Util.php on line 111`
 * Not sure if this has anything to do with the redirect settings in the plugin.
   Also not getting any notification of this test transaction in my Stripe dashboard.
   Can you help, please?

 * Double check and make sure your server requirements meet the plugin requirements:

 * If that all looks good let me know and we can dig deeper from there.
 * Thanks!

 * Hi Nick,
    I see right off the bat that mbstring might be an issue, as I know 
   it is not currently enabled on my server (which I just moved to last week). I
   will enable that and curl and see what transpires. If that fixes things I will
   make a note of it here and mark it as resolved. Thanks for your answer.

 * Installing mbstring and curl in CPanel resolved this issue.

 * Glad that was able to fix your problem!
 * If you ever run into any other issues please let us know and will be happy to
   help.
 * Thanks!
 * P.S. If you get a chance would you mind leaving a plugin review (if you haven’t
   already)? It helps a ton.
