upload allowed_types issue

[eluser]gRoberts[/eluser]
hi all.

One of my users has pointed out that when uploading he gets an error message. When i looked into this, I noticed he was uploading an excel (xls) file.

The problem is that the allowed_types is set to only allow CSV files, but it allows XLS. I have tried uploading an XML file or something else and CI throws an error as its not allowed.

Since when has .xls been the same as .csv?

Any idea's?
