Hi,

please check again that: Did you created a Browser Key? Maybe you created a Server Key instead. If so please create a Browser Key.

If this wasn’t the problem, maybe whitelist your Server IP will help.

hope it helped you.

I tested with Browser Key and Server Key, both don’t work…

My blog test is blog.cideas.com.br

GCM:

Key for browser applications
API KEY AIzaSyC5hKMuZf8XpPbDDg4nMr_A-Ev8aO3MRUg

Ok.
You definitely need browser key. Server key won’t work.

Check this site out. There are thr most common problems listed:

Maybe your server IP is not whitelisted?

I removed the IP from the list and it worked perfectly.

Now, i have a new error.

strange, we can not reproduce this error.
But maybe in the latest version it is fixed, because we changed some code in the options.php.

I’m experiencing the same error
