Hummingbird, Defender plugins issue

Hi so when I install all your recommended plugins available on this site, my site becomes unaccessible. I’ve gone through and figured out that Defender & Hummingbird cause the problem. I really would like to use them because the benefit they supply sounds great, but ya whenever I activate them like I said white page that says my site is unable to load. Help? I’m pretty good with coding so hopefully we can get them working. Thanks!
