That error log might contain some useful info, you should check it.

I've never gone through the example, so I might not understand.

But on openlayers sample page:
http://openlayers.org/en/latest/examples/epsg-4326.html?q=

it makes single layer requests like:
https://ahocevar.com/geoserver/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=ne%3ANE1_HR_LC_SR_W_DR&TILED=true&WIDTH=256&HEIGHT=256&CRS=EPSG%3A4326&STYLES=&BBOX=0%2C-90%2C90%2C0

(Yes, its geoserver not mapserver, but the same params are sent to both.  And it contains SERVICE=WMS and REQUEST=GetMap)

Also, I should note, I've not used mapcache.  I think you should first get mapserver working and forget mapcache for the moment.  Put mapcache on top of a working mapserver.
