But, I have configured the script to accept files with an .accdb extention.

I'm thinking the problem is that the extention is 5 characters ... rather than 4 (like .mpeg) or 3 (like .zip).

The file will upload, but then after it is 100% uploaded, phpUploader takes the temp file and converts it to a fully downloaded one (I think .... that's what it looks like in the code).

The file I'm tryinhg to uplload is named "Scrubv7.accdb"

The error I get is " (1) tmp_name is not available for Scrubv7.accdb"

The error log looks like this ... you can see it's throwing  several errors:

Thanks
