have a plugin that is now giving this error message when activating: Fatal error: Cannot redeclare flush_rewrite_rules() (previously declared in /home/userwco/public_html/wordpress/wp-includes/rewrite.php:106) in /home/userwco/public_html/wordpress/wp-content/plugins/wptrader/wptrader.php on line 219 this was working fine with wordpress 3.4 i think but just tried installing on another blog and now getting this error.. all other plugins are deactivated. i'll pay someone to help me fix this if need be.
