To resolve the mbstring extension not found error with phpMyAdmin, enable the extension.

Open your php.ini file and ensure that extensions are enabled, and pointing to the correct directory:

extension_dir = “c:\php\ext” (or whatever path you installed to)

Then find the mbstring extension, and make sure it is uncommented (that there is NOT a semicolon at the beginning)

extension=php_mbstring.dll

Save, and restart your web server.
