[ka-Map-users] Error using WMS client function

[Open Maps]

Hi all,
I'm new in this ML and my problem is that my mapfile doesn't work 
properly in ka-map pruducing this error:

Warning: [MapServer Error]: msDrawMap(): Failed to draw WMS layer named 
'BMNG'. This most likely happened because the remote WMS server returned 
an invalid image, and XML exception or another unexpected result in 
response to the GetMap request. Also check and make sure that the 
layer's connection URL is valid. in 
/usr/local/apache2/webdomains/openmaps.it/home/htdocs/ka-map-1.0/htdocs/tile.php 
on line 289

Fatal error: Call to a member function saveImage() on a non-object in 
/usr/local/apache2/webdomains/openmaps.it/home/htdocs/ka-map-1.0/htdocs/tile.php 
on line 290

I checked all the documentation that I know in the web but without any 
result...

My mapfile is this:

The /.../tmp/kacache directory is accesible and writable...

You can check my app at
http://openmaps.it/kamap/index_overlay

As you can see the vector layer works correctly but BMNG wms layer is 
not loaded in the kamap interface

Thanks fot your help!
