[Plugin: BulletProof Security] Unable to edit anything

FTP to your website and delete the .htaccess file in your website root folder. This will remove the BPS website security. BPS has built-in troubleshooting capability so you do not need to deactivate it or delete it to troubleshoot problems or issues – you can put BPS in Default Mode.

If you decide to reinstall BPS then take a quick look at the FAQ page here >>> http://ww.wp.xz.cn/extend/plugins/bulletproof-security/faq/

And then take a look at the BPS General Troubleshooting page here >>> http://www.ait-pro.com/aitpro-blog/297/bulletproof-security-plugin-support/bulletproof-security-wordpress-plugin-support/
