Conflict: plugin breaks current user roles

Hi,

I am the author of WP-Clanwars plugin. My plugin’s permissions system relies on logged in user role however it’s empty on certain WordPress installations.

I managed to track down the problem and found that your plugin removes user role on a global $current_user object which creates a conflicts with other plugins and my plugin in particular.

A quick search reveals that both Relic and CDN extensions of your plugin use array_shift which removes user role after it retrieves the value from the beginning of array.

Here is a screenshot: https://www.dropbox.com/s/3wb96l9heuwef41/Screenshot%202015-06-18%2011.16.22.png?dl=0

I can confirm that disabling W3 Total Cache resolves the issue.

Please do not modify global objects and use $current_user->roles[0]; instead.

I would appreciate if you could release an update anytime soon.

Thank you,
Andrej
