 * Hi, after update to last version 3.2.17 on one of my sites i’ve got a fatal error
   during activation.
    `Fatal error: Uncaught Error: Call to undefined function 
   WPDM\__\mb_ereg_replace() in wp-content/plugins/download-manager/src/__/__.php:

 * Hello,
    Hope you are well. Please enable the `mbstring` in your PHP configuration
   which should resolve the issue. However, we are removing the `mbstring` dependency
   in next update. Thank You
