I've got a Ubuntu 12.04 computer with Mapserver and all other software on it. I have tried to set up a simple WMS / Mapcache service but have not succeeded. I can browse to the automatically generated demo page, and they work per se, but all I get are red tiles (i.e. broken)
I think there's something wrong in the configuration files, regarding referencing map or layers.
I get this error message:
[Mon Oct 7 15:41:30 2013].708630 msWMSLoadGetMapParams(): WMS server error. Invalid layer(s) given in the LAYERS parameter. A layer might be disabled for this request. Check wms/ows_enable_request settings.
