This is usually caused by a JavaScript error on your site. Can you take a look in your browser’s developer console and see if there’s an error showing?
It could also be caused by a PHP error. Take a look in your PHP error logs and see if there’s anything in there.
Let me know what you find.
No js errors in dev console.
My php error log shows this:
[29-Nov-2017 01:09:00 UTC] WordPress database error Table 'discovery.wp_woocommerce_sessions' doesn't exist for query SHOW FULL COLUMNS FROMwp_woocommerce_sessions` made by shutdown_action_hook, do_action(‘shutdown’), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, WC_Session_Handler->save_data, QM_DB->query
[29-Nov-2017 01:09:04 UTC] WordPress database error Table ‘discovery.wp_woocommerce_sessions’ doesn’t exist for query SELECT session_value FROM wp_woocommerce_sessions WHERE session_key = ‘1’ made by require(‘wp-blog-header.php’), require_once(‘wp-load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’), do_action(‘init’), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, WooCommerce->init, WC_Session_Handler->__construct, WC_Session_Handler->get_session_data, WC_Session_Handler->get_session, QM_DB->query`
Are there any other JavaScript errors showing in your console?
hi John,
no other errors, apart from a “unreachable code after return statement” warning, caused by the Google Tag Manager’s js (i’ve read it’s something peculiar to Firefox and Gtag).
i’ve got your plugin running fine on a clone of the same site on a completely different server. both are running PHP 7 though (earlier versions cause a blank page on the one where the js error shows up).
hope that helps
