• Hello,

    When I try to update the page or flush it I receive the HTTP ERROR 500. Here is the video https://youtu.be/jUa8tbrUHjE

    I contacted hosting provider. They told me that the problem is not with a hosting but with the W3 plugin as the following error appears in the code

  • I have an identical problem.
    I found that the problem is a Cloudflare plugin.
    When I settle the V3 total to the basic settings all work.
    But when I activate the Chloudflare widget, it does not show the authorization information and other settings.
    I’m off the plugin and I still have a problem. After resetting the whole v3 total add-on, the problem is solved. But I can not use the cloudfare extension.

    Hello,

    Thank you for you reply. I have only the one CloudFlare plugin CloudFlare Flexible SSL — but it is needed to make the site work on https. Did you mean that plugin?

    Was related to the extensions for Cloudflare in W3 Ttotal Cache.

    And here I thought I was the only one with this issue, glad to see it’s not me.
    EXACTLY the same problem here. Seems there’s an issue with this setting up properly.

    At first, I thought it was that it wasn’t logged into CF (duh). Even after authenticating though, it still didn’t work right.

    The (temporary) solution:
    Comment out line 222 in wp-content/plugins/w3-total-cache/Cdnfsd_CacheFlush.php
    Should now look like
    // $engine = $core->get_engine();

    Hopefully they get this one resolved quickly enough ??

    same here. solution here: fatal-error-2749
    summary:

    edit wp-content/w3tc-config/master.php
    set this:
    cdnfsd.enabled: 0

    that’s it
