    This is what I’m seeing:

    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘weaverx_add_ie_scripts’ not found or invalid function name in /var/www/vhosts/noticing-being.one/httpdocs/wp-includes/class-wp-hook.php on line 287

    Hope this helps – looks like it should be easy to fix.

    Cheers, happy solstice-days,



    @weaver will have to comment,

    Are you on the latest version of everything?

    You may want to paste the content of the system info box found in the theme help page


    Can’t find ‘weaverx_add_ie_scripts’ anywhere in any current version of Weaver Xtreme, Weaver Xtreme Theme Support, or Weaver Xtreme Plus.

    This sound like an artifact from some past version of Weaver.

    If you could copy/paste the System and Configuration info from the Dashboard -> Appearance -> Weaver Xtreme Admin ->  Theme Help tab, I might be able to figure out what might have added a WP hook for weaverx_add_ie_scripts.



    Thanks guys, could it be Weaver Show Posts? Anyway, here we go:

    It is not in Show Posts, either.

    But it could be in your child theme if you happened to copy code from an old Weaver version.

    There could be some code with an “add_action(‘something’, ‘weaverx_add_ie_scripts’);
