I tried to disable the wordfence plugin because, no matter

I tried to disable the wordfence plugin because, no matter what, the plugin cold not connect to their API. When I tried to deactivate the plugin it gave me a white screen not only in admin but the whole web site. I had to restore the web site from backup but now I'm back at square one. My question is can I just rename the worfence plugin directory to something else? Any other suggestions would also be helpful. thanks in advance for any help.
