From LimeSurvey Manual

If you don't find the mbstring section, you might have a problem on your hands. There are three possible scenarios:

  • If it's your host provider's server, ask for the activation of that extension in PHP or for further information on how you can activate it - if you have a good administration panel for your server, you may be able to activate it yourself
  • If it's your own Linux server, you may have to re-compile PHP and include the mbstring library. Ask the Linux experts how to do that. However, you can install it using your Linux package manager, which is mostly available in all the Linux distributions nowadays
    • If you are using a version of Linux that supports 'yum' (CentOS, RedHat, Fedora)...
      • ...use the terminal (as a super user) and type: yum install php-mbstring
      • ...make sure to update /etc/php.ini and uncomment the various mbstring params
      • ...make sure to restart apache after installing it: /etc/init.d/httpd restart
  • If it's your own Windows server, search for php.ini on your system, open it with an editor, and search for mbstring. Most probably, the line that contains the string is commented out with a semicolon. Remove the semicolon, save and restart your web server
