I have a few DNN sites and all are randomly showing blank pages, especially when accessed via the pulldown menu. When I say
"blank page"  It shows the page header with the menu, but no modules are loaded. If I refresh the page they all show up again. After 2 or three clicks on the menu, the page is lank again. Any ideas?

I have version 5.04

Thanks you

most likely there is a cache issue, do you have any unusual configuration (multiple IIS worker processes used, or sth. like this)?

Thank you for your response.

No web farm or garden, it's a single IIS machine. It was happening on a previous host and I changed providers hoping to eliminate the issue.

What caching are you describing?

I have gone into Host settings and set Cache Settings to None and pressed the Clear Cache button, but no change.
I have also set Authentication Cacheability to NoCache.

Thanks for your help, I have reported this bug, here is what I found:

This only happens in IE 8, not FireFox

I have tracked this down to some extra garbage characters after </html> in the files that have the missing components. Actually, the components are in the source file and other than the extra garbage characters, the pages are identical. This is hapenning on two different host providers.

Here is the difference:

Good Page ends with this after </HTML>: 0D 0A 00 00 00 00 00

Blank Page ends with this after </HTML>: 0D 0A 00 E6 98 BA E6 B9 B5 E7 91 A3 E6 BD A9

Looks to me like someone is null terminating a string array but sending the entire array contents. This is OK for an application, but the extra binary characters are affecting IE. IE should ignor the extra characters like FireFox, but it appears that it is not. Since 80% of internet users use IE, this needs to be fixed.

James ~

What you're describing would be a very widely experienced problem if were purely a core issue.  It is possible that this is being injected another way.  Is your site accessible so that others could see what else is loading on the page?  Are you observing this site wide?  Does changing to a default skin affect the page output?

Cheers
