Compatibility with PHP 5.6

Hello,

My server updated the version of PHP that run for files with a .php extension to PHP 5.6 and the plugin breaks the entire web with a 500 internal server error when trying to load it.

When you change the PHP version to 5.3 it works OK again. Could you fix that, please?

Thanks.
