I'm preparing a site redesign on BlueHost. Installed W3TC awhile back but now if I try to clear the page cache or all caches, I can't. Server just attempts to connect and then times out with a white screen on a url like http://www.yoursite.org/wp-admin/admin.php?page=w3tc_pgcache
Seems like a server timeout to me.
Is there any way I can make the cache flush?
