can anybody tell me how to resolve this?

Answer 1

The problem is either your PHP installation lacks multibyte extension , either it has not been enabled.

If you installed PHP by yourself make sure you compile it with the --enable-mbstring option.

If you used your package manager to install PHP then check your php.ini file to enable the mbstring extension.

It may be also possible to install an extra package that contains the extension, depending on your platform
