[OpenLayers-Users] Can't display WMS using Spherical Mercator

[Josh Livni]

Well I I don't see anything in your code that jumps out as wrong, which 
isn't to say others might not notice something obvious that I'm missing. 
   It seems to me your centerM should be within your restricted extent, 
and thus not greyed out...

Given you've been working on this a while, I'd consider starting with 
the spherical mercator example, removing the Yahoo and Virtual Earth 
layers, and make sure that works as a very simple demo example.  Then 
start slowly replacing stuff - eg replace the demo zoomToMaxExtent with 
your setCenter, and test.  Then replace the demo WMS with your WMS url, 
and see what happens.  This whole process should take just a few 
minutes, and might help isolate the issue.

Cheers,

  -Josh
