    After last upgrade of Live Composer on one of my sites, I’ve such error:
    <b>Fatal error</b>: Call to undefined function json_last_error() in <b>/wp-content/plugins/live-composer-page-builder-master/includes/display-functions.php</b> on line <b>907</b><br />
    and white screen of death on front page.
    What could be the reason?

    Hi there,
    It means you have a very outdated PHP version on your server.

    According to the docs https://php.net/manual/en/function.json-last-error.php this command is available in PHP version 5.3 and latter. Current version of PHP is 7. Most likely you have version below 5. Please, update php via your hosting panel or contact the hosting company with requires to update php for you. It’s a quick action and it will improve your site security and performance.

    Sorry for this issue, but we can’t support PHP versions that are more than 5 years old.
