Debugging Suggestions?

[hadenp]

I'm getting a '500 Internal Server' and 'Premature end of script headers..' errors in the process of uploading a file. This occurs consistently with files > 2MB but also (very occasionally) w/ smaller files. The target directories are beneath the web root folder, so I don't think it's a permissions issue.

 

I've set the following in my php5.ini:

post_max_size = 8M,

upload_max_filesize = 8M

max_input_time = 360

max_execution_time = 360

 

Trace code/logging reveals that the error occurs even before my upload code is entered (which uses (move_uploaded_file()).  So what would cause that?

 

Any suggestions on how to debug this are very much appreciated!
