Blank page intermittently..WpCache issue? Help

Hello,

Ok, I’ve been using Wp Cache for awhile now and seems to be working fine.

But in the last few days my site comes up blank, but usually just the www version of the site, not the one without the www prefix. It gets solved when I empty the cache.

I’ve read about the ‘flush’ command in one the wp cache files but am not sure that will solve this particular issue.

Does anyone have any ideas?

Thanks!
