hi Margit, thank you. that worked. But I saw another page, that is not working. Also after update.php. The page is admin settings and after clicking Notifications (Benachrichtigungen in german) The tab shows only a waiting progress bar, which is infinite and never ends. Perhabs you also know the solution for this problem? Greetings ---

Could you please do some client-side debugging as suggested here and report back with any error messages that show up? > **[How to debug - BlueSpice Wiki](https://en.wiki.bluespice.com/wiki/How_to_debug)** Thanks, Margit ---

Do I have to install a new module/addon to use this function? ---

As this topic has already been marked as “solved”, maybe we can create a new one for the “notification” issue? As a first hint: Please update to BlueSpice 4.5.3. The error message you have shared refers to some module that has been renamed recently (`ext.notifications.subscription.set` → `ext.notifyme.subscription.set`). A full codebase update will most likely solve this.
