Question

Hello all, I have installed CompareRevisionsAddOn following the installation guide, so:

• unzipped the package, files are in the right place & with appropriate ownership, i.e.
  • bin/compare: chmod 664 (-rwxr-xr-x), chown & chgrp to my username
  • templates/compare.pattern.tmpl: chmod 775, chown & chgrp to my username
• installed the three CPAN modules listed as a dependency

But when I visit the local page calling the 'compare' script, as in: http://my.local.server/bin/compare/TWiki/CompareRevisionsAddOn

I get the following error:

Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.

I am authenticated and everything else works OK, testenv doesn't show any warnings.

Any help would be greatly appreciated!

Answer

If you have the chance to look at your web server's error log file, you might find more information about what went wrong.

Without this information, I can only guess:

• Unfortunately in bin/compare I forgot to remove the path to our perl location which is a bit unusual. So please replace /usr/gnu/bin/perl with the path to your perl location (probably /usr/bin/perl or /usr/local/bin/perl )
• Check if the CPAN modules which you installed can be found by the Plugin:
  cd (twiki_home)/lib/TWiki/UI
  perl -c -I../.. Compare.pm
  If this gives no error, the modules are installed correctly

Sorry, should have mentioned that the error_log didn't show any errors. Anyway, I checked the script and indeed the path to perl was the problem. Now all works as expected. Thanks a bundle, now I know what to look for in the future when these problems occur!
