[Chameleon] Manage WMS Servers widget shows "cache_mlt" error s, results in no WMS data layers

[Jennifer Zeisloft]

Hi Bart (and list),

Thanks so much for the suggestion - I don't remember placing my old
chameleon.xml file in the new version - but adding the code got rid of the
mlt_cache error.

Unfortunately, it does not seem to be related to the WMS problem - which is
what I really need to solve.

Has something changed since the last version of Chameleon that might cause
WMS servers to lose their layer lists in the Explore WMS Layers window?  The
refreshed servers are still listed as connected, but display the same way a
disconnected server displays except that a Service Title is still shown.  It
is not only our WMS servers, but *every* WMS server that is refreshed.  If
the server is not refreshed, there is no problem.

I made the assumption that refreshing a server grabs a new capabilities
statement.  I checked for differences and found only two - one having to do
with the SYSTEM definition and one having to do with the mapserver version
being used:

BEFORE:
<!DOCTYPE WMT_MS_Capabilities SYSTEM "
http://schemas.opengeospatial.net/wms/1.1.1/capabilities_1_1_1.dtd"

<!-- MapServer version 4.6.1

AFTER:
<!DOCTYPE WMT_MS_Capabilities SYSTEM "
http://schemas.opengeospatial.net/wms/1.1.1/WMS_MS_Capabilities.dtd"

<!-- MapServer version 4.8.1

The tricky thing is that ONLY our files showed these differences.  Other
refreshed server capability statements showed no difference between the
"before" and "after".  Perhaps I am on the wrong track?  Or perhaps this
could be part of the answer?

I am running out of ideas with my limited understanding of exactly how the
widgets work and I truly appreciate any help that can be provided.

Thank you!
