    I’m getting a critical error when trying to duplicate a post. I contacted my hosting support and here is their recommendation:

    From the stack trace it seems that the issue might not be with divi but with W3 caching plugin. What I can recommend is you contact the support of W3 and provide them with the stack trace so they can look into it.

    Here is the stack trace:

    #0 /home/ligcoach/public_html/wp-includes/class-wp-hook.php(308): W3TC\Varnish_Plugin->varnish_flush_post()

    #1 /home/ligcoach/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters()

    #2 /home/ligcoach/public_html/wp-includes/plugin.php(517): WP_Hook->do_action()

    #3 /home/ligcoach/public_html/wp-content/themes/Divi/core/components/init.php(88): do_action()

    #4 /home/ligcoach/public_html/wp-content/themes/Divi/core/components/PageResource.php(981): et_core_clear_wp_cache()

    #5 /home/ligcoach/public_html/wp-content/themes/Divi/core/components/PageResource.php(921): ET_Core_PageResource::do_remove_static_resources()

    #6 /home/ligcoach/public_html/wp-content/themes/Divi/core/components/PageResource.php

    Hello @jatjai

    Thank you for reaching out and I am happy to assist you with this.

    Can you please share if the option “Enable reverse proxy caching via varnish” is enabled in Performance>General settings>Reverse Proxy, and if so, have you specified the IP addresses of your varnish instances?

    Also, pleas let me know which method you are using for duplicating posts.
    Thanks!

    Hi – Yes, it is enabled and there is a specified IP address.

    When duplicating posts – I go to Posts and hover over the post title and click on “Duplicate”. When I do this, it shows a page with “There has been a critical error on this website.”

    Hello @jatjai

    Can you please try a quick “fix” and update /wp-content/plugins/w3-total-cache/Varnish_Plugin.php line 57 to:

    public function varnish_flush_post( $post_id, $force = false ) {

    Let me know if this helps!

    Thanks!

    Thank you for your response.

    I contacted my hosting support with this fix – they mentioned I should uncheck the “Enable reverse proxy caching via varnish” since they don’t work with the varnish servers. I tried that and it seems to have solved the issue.

    Thanks for your help!
