I figured this out but you have to edit one of the plugin’s core files which sucks but it’s all we can do for now.
In the file ClearFavoritesButton.php (plugins/favorites/app/Entities/Favorite/)
1. Find:
$out = '<button class="simplefavorites-clear" data-siteid="' . $this->site_id . '">' . $this->text . '</button>';
and change to:
$out = '<button class="simplefavorites-clear" onclick="FavReload()" data-siteid="' . $this->site_id . '">' . $this->text . '</button>';
2. In footer.php add:
<script>
function FavReload() {
setTimeout(myTimeFunction, 1500);
}
function myTimeFunction() {
document.location.reload(true);
}
</script>
The 1500 equals 1.5 seconds, you can change that if needed. Only tested this on Chrome so no guarantees it’ll work on all browsers.
