I just upgraded to MT3.2, and a long-standing bug I had in the old 3.1 versions is still not fixed. I am unable to upload files with MacOS X and Safari, although I can upload files with other browsers. I get an error message:

"Safari can’t open the page “http://myblog.com/cgi-bin/MT/mt.cgi�. The error was: “POSIX error: Invalid argument� (NSPOSIXErrorDomain:22)"

I worked around this but I was kind of hoping it was fixed in the new version. But maybe it's something in my local configuration, but I don't have any mods to Safari or anything else I can think of that would cause such an error.

Does anyone have any ideas on what is happening?

I just ran into this myself.. The error happens if Safari can't write to it's Cache.

Take a look in Library/Caches/Safari and make sure the folder exists. If you've disabled the cache by replacing the Safari folder with an empty read-only file, or a link to /dev/null (like I was doing), or something else, you will get this error.

Once you delete this file/link/etc., click Empty Cache from the Safari menu to set up the cache again.

Good luck,
