Something weird on my site. Each time I've tried installing either W3 Total Cache or WP Super Cache, the plug-in installs fine, but immediately I click on the Activate link, the browser window goes blank. I can't access any admin pages, each time I see absolutely nothing (and if I View Source, it's also blank). Only using FTP to delete the plug-in will allow me to log in again.
If this was just the one plug-in I could maybe understand it. But it happens with either of these two caching plug-ins.
Can anyone help?
