Well, “empty cache” is a one-time option, which after activation triggers the lyte cache to cleared and then is switched off again.
I have already seen occurrences of lyte’s cache not being entirely cleared (not sure why), but as this is stored as post_meta, you can tell WordPress to show it as a custom field by adding this code in a small helper plugin or in your (child) theme’s functions.php;
if (is_admin()) {
add_filter( 'is_protected_meta', 'lyte_unprotect_meta', 10, 3);
}
function lyte_unprotect_meta($protected, $meta_key, $meta_type) {
if (strpos($meta_key,"_lyte_")===0){
return false;
} else {
return $protected;
}
}
If you do that and you go to the “edit post” screen, then you will see a custom field with a name that starts with _lyte_ and then the YouTube id (e.g. _lyte_wHENTMGVb74). Go to the post that has the “youtube device support” video, delete the _lyte_<videoID> custom field, update your post (confirm there’s no custom field _lyte_<videoID> any more and then visit the page again to have lyte-refetch the info from YouTube (api v3).
Let me know how that works! ??
