The error message is

Errors Returned While Uploading
Unknown filetype rejected
MIME type not allowed: image/jpeg

Hi people,

My XOOPs version is 2.0.13.2 and I am feeling strange
about the Image Manager.

Whenever I upload "image.jpg" - no problem but
problem is I cannot upload the same file with
capitalised ".JPG" (image.JPG). So I have to
small-letter it from "image.JPG" to "image.jpg" manually
just to upload.

I was trying hard to look for the file extension
configurations but no avail.

Can some kind person point out to me where
I can rectify this?

Many thanks!
