Doesn’t work well in combination with Redis FPC

  • Hey Guys,

    One of my clients had some complaints about forms that ended up in an infinite loop (spinner keeps turning). The odd thing is that it only happens when you try to sent a form from a smartphone. So I tried to reproduce the issue and indeed, I ended up with an infinite loop as well.

    I activated WP Debug mode and saw the errors below:

    [14-Apr-2021 07:12:57 UTC] PHP Notice:  Undefined index: HTTP_HOST in /var/www/stoptandartsangst.nl/htdocs/wp-content/plugins/wpcf7-redirect/classes/class-wpcf7r-updates.php on line 40

    Redis FPC was enabled on this site. So just to test things out I disabled Redis FPC and afterwards it worked as intended.

    Do you have any suggestion on how to let this plugin work properly with Redis FPC?

    Thanks,

    Jordy
