Fatal error: call to undefined function mb_strtolower() in OpenCart

Question

I am using opencart 1.5.6

I had a major server meltdown this week and had to do a mirror restore of the server. Now all is back to normal except now in opencart when I try to login as a customer or go to checkout I get this error and have NO idea how to fix it.

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Fatal error: Call to undefined function mb_strtolower() in public_html/vqmod/vqcache/vq2-catalog_model_account_customer.php on line 46

Re-installing opencart isn't an option so I'm stuck on what to do.

You need to install/enable mb_string PHP extension. Usually you just need to enable one as mb_string should be shipped with your PHP. See PHP's conf.d or php.ini (depends on used version).
