After I download the Oauth2 plugin, I can see it in the list of plugin to be installed. However, once installed, I will not be able to access the system anymore. It will give error localhost is currently unable to handle this request. Is there any solution?
Authentication: Oauth2 Localhost unable to handle the request
You would need to check your PHP and web server error logs for any related errors. That is simply an indication of a fatal error somewhere.

KevinTheJedi I think this have something to do with the themedost that I am using. previously I installed without themedost and it works fine. I can't figure out how styling/theme can affect the plugin installation. Other plugin works fine.
Ah, then I cannot really assist. Once you modify the codebase or use 3rd party mods/plugins any issues are up to you to debug and fix.
Your best bet is to either remove the theme or try to look at your error logs and see what’s going on.
