I'm a user of WP; my son installed it, but is unavailable to help right now.
When I try to upload a PDF to my blog, it then appears as a file named: http://mysite.com/wordpress//../../../tmp/myfile.pdf instead of the usual http://mysite.com/wordpress/wp-content/2008/NN/myfile.pdf.
The "tmp" file is not available for use, though it then appears in the Browse window. Attempting to access it after inserting it results in a "404-Not Found" error
Also, all of my uploaded previously-uploaded PDF's fail to appear in the Browse window. (They ARE still functional, but I can't access them via the Browse button.)
Any thoughts, or has anyone had this happen and fixed it? Thanks.
