 arūnas Burdulis - Problem while using "Try It" from Library Browser  7/26/2006; 10:29:18 AM (reads: 166, responses: 2) We are getting the following error when trying to work a sample problem (by clicking "Try it") in the "Library Browser". By looking at the code at around line 462, it appears that WW expects some "global problem" (\$globalProblem) to be defined and produces the error below, when it isn't defined. Are we missing something here in our setup or configuration? Webwork 2.2 here as released in February, running on Debian stable, Apache 1.3. Thanks for any hints or suggestions, Sarunas Error messages sourceFilePath is unsafe! at /var/webwork2/lib/WeBWorK/ContentGenerator/Problem.pm line 462.

Before updating save a copy of the webwork2/conf directory e.g  cp -RPpi conf conf.save After updating you will need to compare global.conf, database.conf and webwork.apache-config with their .dist versions (global.conf.dist) and make any necessary additions to those files by hand. Here is a long thread discussing exactly the problem you are facing: <| Post or View Comments |>
