I checked your website and you have WordPress 3.3.1 installed, which was released on January 3, 2012. WordPress 3.3.2 was released on April 20, 2012. The BPS plugin requires at least WordPress 3.7 and I would imagine the same thing would apply with all of your other plugins and your Theme. So I recommend that you do these steps below.
Use FTP or your Web Host Control Panel File Manager and rename the /plugins/ folder to /_plugins/. Manually delete the root .htaccess file and the wp-admin .htaccess file. Login to your website, go to your WordPress Plugins page to automatically deactivate all of your plugins, rename the /_plugins/ folder back to /plugins/, upgrade WordPress. Try to activate plugins one by one. If they fail to activate then manually delete that plugin’s folder. Then reinstall that plugin using the WordPress plugin installer.
