Using WP-Filebase with IE7 or IE8 if you go to file listing in WP Filebase, click on a PDF, and view it, no worries. Click on the back button and try to view it again - you get the following error message:
file does not begin with '%pdf-'
If you clear the IE browser cache, you can view the file again - once. Then you get the same error message and have to clear the cache before viewing the file again.
Another user posted a similar problem with the recommendation of Disabling HTTP caching (WP Filebase Settings>Download) but no luck for me...error still persists.
Any recommendations? I wish I could ignore IE, but still too big a user population both with the client and their end users.
