 * Hi I’ve been experiencing a lot of 500 server errors since 4/14/14 after a lof
   of head scratching i’ve tracked the problem down to rpx disabled it an poof the
   500 server errors are gone. I also found a conflict between RPX and another plugin“
   NK Google Analytics”
 * Fatal error: Cannot redeclare is_login_page() (previously declared in /…/wp-content/
   plugins/rpx/rpx.php:190) in/….wp-content/plugins/nk-google-analytics/NKgoogleanalytics.
   php on line 22
