do_filter :), that can’t be right.
If it is then it is an embarrassing bug.
Not sure how it passed, will release an update shortly.
For now pls use the dirty fix.
WP_PLUGIN_DIR/wc-fields-factory/includes/wcff-builder.php
Replace the ifcondition block (LN : 1441) with the following.
if (has_filter('wccpf_before_field_rendering') && has_filter('wccpf_after_field_rendering')) {
$before = apply_filters('wccpf_before_field_rendering', $_meta);
$after = apply_filters('wccpf_after_field_rendering', $_meta);
$html = $before . $_html . $after;
}
I will make sure the fix will get into the sub sequent releases.
Yesterday I did a silent update for including intro video, with that I have released the fix as well.
