[ww-devel] The library browser not updating problem

[Gage, Michael]

I’d check the parameter xml_command in the HTML page for the library browser.  If you look at
line 318 in instructorXMLHandler.pm it seems the most likely reason for the failure is that
the xml_command value is undefined.

Take care,

Mike

Right now we're only using webwork's internal authentication.

For both authentication and the last one, it might help to look at the apache error.log.  Even then, you may need to modify webwork to show errors instead of just reporting "there were lots of errors".  That's how we tracked down a mismatched perl module problem.

I am seeing this in the error logs:
