Thomas,
*note I noticed that ArcCatalog reports the LatLongBoundingBox as 0, 0, 0,0.
This is probably important...
I realize that mapcahce does not project. For testing I completely removed my
grid, source, and tileset that is in county coordinates. My other cache is in
UTM 15, The only grid I have advertised is UTM15 such as:
<!--<grid>WGS84</grid>-->
<!--<grid>g</grid>-->
<grid>UTM15</grid>
So here is what I have:
Demo: The demo site works fine. Here is an example request that works
http://10.0.8.116/mapcache/?LAYERS=MNSOUTH11&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A26915&BBOX=438394.0589,4887031.0797,471162.0589,4919799.0797&WIDTH=256&HEIGHT=256
WMS in ArcCatalog: Doesn’t work
The lat long bounding box is 0,0,0,0. Furthermore ArcCatalog advertises EPSG:
26915 (which is correct) , EPSG: 900913, EPSG 26915 again?, EPSG: 3857. How
can I remove the other projections. I only want to serve 26915.
* I did try to change the coordinate system that ArcCatalog / ArcMap requests
to UTM 15. Mapcahce still did not work
WMS in QGIS: Doesn’t work.
In the properties for the service (root layer) I noticed the WGS 84 Bounding
Box is empty. However, the layer MNSOUTH11 does have a valid bounding box
WMTS in QGIS: Works.
When adding the WMS layer in QGIS, I noticed I could switch between layers
(wms) and Tilesets (WMTS?). The tilesets work in QGIS.
********************************************************
When I did have the County Map service configured, nothing worked. Not even
the demo. I didn't even get any pink tiles in the demo, and firebug reported
that it was not even trying to request anything.
Let me know if you have any thoughts as to why the WMS service isn’t working.
Thanks for all your help

I've never tried the wms service in arcgis...
what I do know is that mapcache advertises all known grids in the wms root
layer, however only the actually cached grids are advertised for each
individual layer (that's what the spec requires, although it does not fit very
well with cached layers). I wouldn't be very surprised arcgis chokes on that.
Check your server logs for the requests actually being sent out by arcgis, that
will at least tell you if the correct grid is being used.

need more info... mapcache itself does no projection handling, the grid srs is
only used as a key to lookup which tiles to return, and is forwarded to the wms
server as is. Right clicking on a pink tile in the demo page and opening the
image in a new window might give you more info to help debugging.
