I have a customer who's site is displaying blank pages ... this happened once before and I had to reset w3 total cache and it restored the site.
Unfortunately now I can't even login ... I found an old blog post where I was able to at least get a page to pull up and display the login menu, but any attempt to login gives me a blank page.
Can I disable w3 total cache via ftp? I need to find a way to shut the plugin off so I can at least login to troubleshoot.
Thanks ... Scott
