cache creating website to break

Everything on the site (WP, plugins, theme) are all up to date.

So, when the cache is on, the whole site falls apart. The menu disappears, the images become HUGE, the text gets bounced all over the place.

When I turn off the cache. The site is fine.

So, I thought I would clear the cache and delete everything I could and try again. But that didn’t fix the problem.

So, for now, the cache is off. Which is a pity. You are my favorite caching system.

Any idea why the cache would cause the page to act so erratic.

I can post a before after screen shot if that would help, but don’t want to “break” the site intentionally during business hours.

Thanks.
