I have the Cache enabled and set to a 5 minute lifetime. When I log out > then access any page as Anonymous > then try to access that same page again (even a Refresh) > I get a blank page (no errors displayed or logged). Then I'm kind of trapped because I can't go Back or go to any other page I've visited before.

It's gotta be a problem with the Cache somehow or the information sent to it. If I disable the Cache - no problems. If I monitor the Cache in PHPMyAdmin > delete the visited page entry > access the page one more time - no problem. I want to use the Cache though! :-)

I have two installations of Drupal to monitor. On my main one, the one with this problem, I have many modules and customizations. On the other installation, my secondary, I have no modules or customizations. On the secondary I cannot produce this problem so it leads me to believe it's all my modules and customizations right? So I disabled everything that I thought would affect this - no success.

On another post, http://drupal.org/node/85835, I've attached my SQL dumps for the Cache from the broken site and the working site. Also a screenshot from PHPMyAdmin showing the entry (for the user/register page) I can delete and make things work one more time. Those little entries are the problem! (internally somewhere)

I am hoping that someone knows how to analyze this information and can find the bug. Or has anyone else ever had this problem? Any thoughts would be greatly appreciated. Thanks in advance :-)

I came across this exact issue last week. I saw that I had this message in my watchdog"

"Unsupported encoding 'ISO-8859-1'. Please install iconv, GNU recode or mbstring for PHP."

I am not sure, but I think that the cache is encoding for faster recall, but if your server does not have the above libraries installed (my host won't at the moment, they say it affects the accuracy of CPU and memory tracking).

Are your two sites running on the same server or host, or are you getting this watchdog note?

Both sites are running on my local testing server. I use Apache2Triad. My phpinfo() says I have mbstring enabled. When the cache is enabled and I experience this problem no errors are logged to the screen or in the admin sections (is there somewhere else I should look?). My site will be going live soon and I'm curious to see what happens on my 1and1.com web host. Anyway, I'm still experiencing this problem locally.
