Note: You are currently viewing documentation for Moodle 3.3. Up-to-date documentation for the latest stable version of Moodle is probably available here: admin/environment/php extension/mbstring.
If you want to have mbstring work on a LAMP server with yum (Fedora, Redhat, Centos) or apt-get (Ubuntu, Debian) then do this
1) As root from the CLI yum install php-mbstring or in the apt-get case apt-get install php-mbstring
For php7 on Centos do: "yum install php70-mbstring"
Then restart Apache
either /etc/init.d/httpd restart or possibly /etc/init.d/apache2 restart
Then check your server Environment again and the whinge from Moodle should have gone away and rewarded you with a nice tick or such-like.
To enable the mbstring library in Windows package installations of Moodle:
- Open the php.ini file found in the moodle/apache/bin folder or Windows folder
- Find the line:
- Remove the
;at the beginning of the line
- Restart apache if necessary
Note: This page needs to be enhanced by adding corresponding instructions for other kinds of Moodle installations.
- Using Moodle php_extension mbstring is recommended to be installed/enabled forum discussion
