Hi again,
Well that is strange indeed. I blindly assumed the code was failing on all
uploads, but you claim it only fails on pdf. Sorry, my bad. :-)
Summarizing:
1) Your upload script works fine for all files except (some) pdf.
2) In your log you can see the call to the upload-script for all succesfull
uploads, but NOT when uploading this pdf. You find NO record in apachelogs
at all.
If this is the situation, my guess would be that apache2 is somehow screwing
up before php gets involved.
Can you check your apache errorfiles?
Anything out of the ordinary?
Regards,
Erwin Moller
