You must register your "misc_"!

Out of hand, I do not know how you do it. But you can find out
by looking through the sources in the "App" folder.
Search for "misc_".

"SCRIPT_NAME" is the name of the CGI script that started Zope,
provided you use "pcgi" to start Zope (what you probably do not...).

When you do not connect Zope via "pcgi", "SCRIPT_NAME" is empty
(as it should be).

Using Zope with "pcgi" is old, "SCRIPT_NAME" is deprecated (as
it does not play well with virtual hosting).
The modern replacement is "BASE1".

Usually, products install their "misc_" in a global "misc_" registry
under their name. The URL is that of the registry ("misc_")
followed by the product ("MyClass") followed by the key defined
in the products "misc_".
Apparently, your product does not register its "misc_".
