[MS4W-Users] Mapserver displays raster with blank tiles

[Emmanuel Adegboye]

Hello Mark.

Thanks for your response.

I did what you suggested and I found this line in the error file:

"[Thu Sep 26 12:09:42 2013].891000 Corrupt, empty or missing file
'./data/srtm.tif' for layer 'srtm' ... ignoring this missing data."

Apparently, I didn't properly define the location of the file path relative
to my map file, so I used the absolute path instead and it works fine now.
Thanks a lot.

Regards,

Emmanuel Adegboye
