... this solution can help you.

1. Open php.ini in your PHP folder.
2. Find the extension below and uncomment (remove the ;)
    
   ;extension=php_mbstring.dll ---->  change this to extension=php_mbstring.dll
3. If you want, although not necessary, you can default the mbstring language setting to English. Just find the mbstring.language = and change it to mbstring.language = English.
