When I try to log in to my back end or pull up my blog I get the following Error Message: Fatal error: Cannot redeclare wp_pagenavi() (previously declared in /home/wehypey2/public_html/wp-content/plugins/wp-pagenavi/wp-pagenavi.php:30) in /home/wehypey2/public_html/wp-content/themes/mainstream/includes/theme-functions.php on line 51
Does anybodt know how to resolve it? How to go back to a past snapshot??
Thank you in advance for any assistance you can offer,
