Yet another Excel file upload mime type problem

[eluser]raenk[/eluser]
I have searched and checked every (i think) excel related issue with the upload class and mime type check and still haven't found a solution.

When trying to upload an excel file the upload errors out stating the file type is not allowed, which of course is.

I checked the array at the mimes.php file, added some new to no avail. Then I print the $_[FILE] element holding the type uploaded and it had the audacity to print a type which IS included in the mimes.php file.

Can't fight that.

Any pointers ?

Thanks
