Error when updating plugin


When I updated this plugin from the admin dashboard it crashed my whole network of sites. I removed it from my FTP and tryed to manually transfer it to plugins folder. When I try to activate this plugin I get the following error code.

Fatal error: Cannot redeclare my_scripts_method() (previously declared in /home/talointr/public_html/wp-content/themes/bigbangwp/includes/bra_theme_functions.php:404) in /home/talointr/public_html/wp-content/plugins/sitewide-privacy-options/sitewide-privacy-options.php on line 83
