FIXED: In BT-server/bt_v15/bt_app change line 431 of file: bt_pushNotifications.php <<OLD>> //if(strtolower($userfile_type) != "application/octet-stream" || strtolower($file_ext) != "pem"){ <<NEW>> if(strtolower($userfile_type) != "application/x-x509-ca-cert" || strtolower($file_ext) != "pem"){ If you want to see how the old code was broken; I inserted this line to get visible output in the control panel that showed what the variables were set to. It was then apparent where the mismatch was: $strMessage = "<br/>file_ext is: " . $file_ext . " filename is: " . $filename . " userfile_type is: " . $userfile_type; Hope this helps someone!

Thank you @WolfTimJ! LA

hi, Tim your solution seems to be for the self-hosted users, what if I am a buzz-server host one, I can't access the file: BT-server/bt_v15/bt_app ... in this case, what can I do? Thanks for your help. Best Regards, Skywalker

Thank you, Tim! Also, thanks for already reporting this on the BT v3 error listing. @Skywalker -- you will have to wait for the BT Team to make the fix. -- Niraj

hi,Tim Thanks for your solution, Now I can upload the .pem file to my self-hosted server, But I still can't push notification to my test devices, it's said that no device registered, I remember, when I upload the .pem file to the Buzz server, it immediately shows that my iPhone and iPad are registered in the control panel, why there's a different thing in my own server? Do you know what's wrong with this? Thanks, SKywalker.

In your core settings ---> push notifications. Be sure you Prompt To Enable Push Notifications is set to yes, and reset the Register Device URL if it might have been changed. Tim

@Tim- Wow! This was really helpful. At first i thought that i missed something while creating the .pem file. Tried creating it couple of time and then decided to take a look at the forum and hit this post. I am happy to inform you that the .pem file got uploaded perfectly. Thanks a lot.

I have finally got a .pem file but Buzztouch won't let me upload to my control panel grrrrr!

The fix is the first message in this thread.

I'm not self hosted though

Fix for non self hosted - upload your pen file through windows and it works Don't know why but it does!
