Hi guy's
I am smith adam from Alaska, America. I recently created my website on wordpress. My site is Login-gmaildotcom and my problem is that whenever i try to install any of plugin then this message is showing(An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums). I am not a technical person and don't know how to solve this problem. I tried to contact to my hosting provider. But they are saying that it's not our fault. So, please help me asap.
And i am wating for your reply. SO pls help me

You should switch to the twenty-sixth in theme and if you still get the problem, you need to ask this question in the Wordpress.org support forums

Sorry sir but it's not working yet........and i tried to contact wordpress.ord. But no reply

If the problem occurs with twenty-sixteen then it is not a theme issue.
If your host can not help you, I would suggest moving to a new host.
Good luck.
