Hi @Fosters, it seems like this may have been broken on the most recent IPB update. My users are stating that while they get the notification counter showing up at the top, it isn't there when they click to expand.
In the logs I'm seeing:
RuntimeException: (0)
#0 /home/./apps/forum/applications/core/modules/front/system/ajax.php(483): IPS\Notification\_Inline->getData()
#1 /home/./apps/forum/system/Dispatcher/Controller.php(107): IPS\core\modules\front\system\_ajax->instantNotifications()
#2 /home/./apps/forum/system/Dispatcher/Dispatcher.php(153): IPS\Dispatcher\_Controller->execute()
#3 /home/./apps/forum/index.php(13): IPS\_Dispatcher->run()
#4 {main}
Backtrace:
#0 /home/./apps/forum/init.php(1034): IPS\_Log::log()
#1 [internal function]: IPS\IPS::exceptionHandler()
#2 {main}
Apologies if this isn't related to your app but haven't had any success debugging on my own.
