Hi,
When WP Super Cache is enabled, the MIME type for PDFs appears to be text/html instead of application/pdf. This causes the browser not to display them properly (they get displayed as a garbled text file, rather than a PDF).
The problem disappears when WP Super Cache has caching disabled, so I’m fairly sure this plugin is at least part of the problem.
Adding *.pdf to the list of URLs not to cache, doesn’t seem to help.
A web search shows other people having the same problem, but I can’t see a solution that works.
Any ideas? Thanks.
