Hello,

Push notifications when are not supported should be completely OFF but am getting this error on any activity on my testing forum. (iPhone iOS 12.1 / Safari)

Whit my admin acount I don’t see the error but with any regular account the error exists.

We already have code which should prevent sending the notifications before it gets to this stage in the code:

public function isPushAvailable()
{
   $options = $this->app->options();

   return (
      $options->enablePush
      && $options->pushKeysVAPID['publicKey']
      && $options->pushKeysVAPID['privateKey']
      && $this->isReceiverSubscribed()
   );
}

So that would imply that you have push enabled, here:


Or when you get to that option, do you see the option is greyed out and a red error message? Was it enabled previously? There was a bug previously which would have allowed you to enable the option even if your server didn't support it, but that is fixed now.

You may just need to verify that the option is disabled and then hit "Save" to ensure that overwrites the previous enabled state.

Yes, I enable it on Beta 3 but now in Beta 4 it not enabled!!

This is how the option looks:

 

[Chris D]

I suspect you enabled it in Beta 2 actually (we pretty much released Beta 3 and 4 within an hour of each other and we fixed it before releasing Beta 3).

But that's ultimately what the bug was. You should never have been able to enable it in the first place.

Just hit "Save" on that page and the error will go away. Either that, or get your host to enable the gmp extension

 

[Fethi.dz]

Ok. now after saving the options the error message gone.
