Cause
lcfirst function is missing in your PHP version. It can happen if your PHP version is older than 5.3.Solution
Request your host to switch PHP version from PHP 5.2 up to PHP 5.3 or newer (PHP5.6 or PHP7.2).Note: Magento versions prior to 1.9.3 may need additional PHP compatibility patches. See PHP compatibility patches in this list
