Support » Plugin: Product Feed PRO for WooCommerce » A variable mismatch has been detected

  • Resolved cath88


    Hi, desperately trying to create a new feed (using the most upto date version) and evertime Im about to complete the process I get the error:
    “A variable mismatch has been detected.”
    Very unhelpful error as I have no information whatsover where I should be looking or exactly what is wrong.

    Some assistance would be most appreciated

    Yes that is correct.

    I also noted that I got it working in my live environment, but then saw that I had different WP versions running in the different environments.

    In DEV (that dosen’t work) we are running 4.9.9.

    On LIVE (that work) we are running 4.9.8.



    Thank you very much, this latest update has fixed the problem. Much appreciated. Happy holidays

    Just before WP pushes out their own fix πŸ™‚

    All the best,




    I also have this problem when I try to update filters…

    WP + Woo + WPML all updated to the latest version. :/

    We have just reached out to the support team of WPML to see what is going on. If it is something at their end or that the conflict is caused by us doing something wrong.

    As soon as we know more and the issue is resolved I will let you know.

    All the best and have a great weekend,

    I’m stuck with this error as well.
    When i try to add a filter it gives the error “A variable mismatch has been detected”.
    I have WPML installed, not a currency switcher.

    Looking forward to have a solution πŸ˜€

    We haven’t heart back from the developers of WPML yet but tried fixing it ourselves today. Could you download the latest release of our plugin (4.3.2) and give it a try?


    Hey Eva,

    it is fixed!
    Thank you, great plugin and great support!

    Much love,
