Getting an problem where whenever you attempt to upload a pdf in wordpress, no matter size - it gives an http error. Images upload fine. Upload limit is 2mb, but that should not be an problem when the pdf is under 1mb. Wordpress continues to be up-to-date and problem remains. Any ideas?

Re-size in php.ini setting upload file:

upload_max_filesize = 10M publish_max_size = 10M
