 * I love this firewall! I use it on 3 other websites, however, when I add it to
   my current website, the website breaks and I get this error message.
 * What does this mean? Is there a conflict with another plugin or is the theme 
   I’m using incompatible?
 * I’m using the Pricerr theme from sitemile.

 * Can you try changing your theme to see if this makes a difference?
 * If not, can you disable each of your plugins, 1-by-1 until this message disappears?
 * It looks like something else is calling the WordPress action hook “wp_login”,
   but they’re not passing in the same parameters as WordPress does.
 * This means that when our function gets called, it dies because the 2nd parameter
   isn’t being passed through as is standard. The best solution here is to find 
   the offending plugin/theme and show them this post and ask them to fix it.

 * Thank you for your response. I am pretty sure I know what plugin is not working
   with you guys. I forwarded them the error and told them I want to be able to 
   use your plugin because it’s the best!
