    Hi @segmant,

    Thank you for using Hummingbird and reporting this issue.
    We are aware of this issue and have a fix for this which will be available in the next update. In the meantime could you go to Page Caching settings in your network admin and turn on “Clear full cache when post/page is updated”. Please let us know if this resolves the issue.

    Cheers,
    Calum

    Hi Calum

    Yes took that step to switch the “Clear full cache when post/page is updated” but also found a previous user with the same issue and added the 

    if ( ! $metas ) {
    continue;
}

    after line 1016 in the /core/modules/class-module-page-caching.php

    cheers for the quick response
