I have installed the MobleFrontEnd extension in my wiki. It was working perfectly. But after installing some other extension, I updated wiki for updating the new tables to the database. After that clicking on "Mobile view" in the footer gives me an error: 'Fatal error: Call to undefined function mb_convert_encoding() in /home/wiki/html/includes/HtmlFormatter.php on line 66. How do I solve this?

I found the solution

The error:

Fatal error: Call to undefined function mb_convert_encoding()

was because of the absence of php Multibyte Support in the server.

By installing php-mbstring-5.3.3-27.el6_5.2.x86_64.rpmand restarting apache solved the issue.

DONT FORGET TO RESTART APACHE. Because I wasted a lot of time without the restart.
