    Hello,

    The old version of Master Slider plugin or some 3-rd party plugin can cause such issue. Please try to disable all plugins, except woocommerce and then update and activate Visual Composer plugin, if all will be fine activate your plugins one by one to find a reason of the problem.

    In this case it would be the NEW version of js_composer in combination with another plugin!
    Is this the only way to filter out “BAD” plugins?

    Hi,

    Unfortunately yes, we can’t able to find what cause the issue.

    One way is to disable all the plugins and activate one by one to find which plugin cause the damage.

    Another way is, turn on WP_DEBUG in wp-config.php, it will tell exactly what cause the fatal error, https://codex.wordpress.org/WP_DEBUG

    If you can’t able to login to your website means, just try to rename the plugins folder to plugins1 and then login to your website.

    Let us know,

    Thanks,
    laranz.
