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

[Jennifer Zeisloft]

Hello All,

I recently upgraded ms4w and chameleon to the versions most current at the
time: ms4w 1.4.1 and chameleon 2.4.  Since that time, the Manage WMS Servers
widget "inside" the Add WMS Layers widget is returning a series of errors
with the same messge:

cache_mlt not found. Returning default value.

The biggest problem is that any servers that are refreshed or added show
only the upper most segment of the tree in the Add WMS Layers dialog - i.e.
the title appears, but none of the layers appear and nothing can be added to
a map.  I am guessing this is related to the cache_mlt error, but not
certain how.

I searched the archives and took a look at the mlt.php file, but don't
understand how this would affect WMS servers.

A look at the Apache error log shows a couple of unusual errors that I do
not know the origins of and which also seem related to the WMS problem:

Premature end of script headers: php.exe, referer:
http://.../chameleon//common/phpwms/manage_servers.phtml?sid=445925887dba6&callbackFunction=myUpdateServers

File does not exist:
C:/ms4w/apps/chameleon/htdocs/skins/default/css/cwc2.css, referer:
http://.../chameleon//widgets/WMSBrowser/WMSBrowser.php?template=mapbrowser_iframe_en.html&sid=445925887dba6
(none of the icons, etc. appeared to be missing...)

If anyone should have a suggestion as to how to get WMS layers to appear in
the Add WMS Layer dialog or how to get rid of the cache_mlt error, I would
greatly appreciate it!

Thanks in advance for your help!
