Discussion and Answer

We tested over 100 plugins for TWiki-5.0 compatibility. We have not yet tested the WebPermissionsPlugin.

Your help in testing is greatly appreciated, many more plugins need to be tested. If plugin use unofficial function or method calls they might break on TWiki upgrade. You can support the community by providing a patch to fix an issue if there is one.

We invite you to get involved with the community, it is more likely you get community support if you support the open source project!

Had the same issue as the original poster. Seems that there is a problem at the lib/TWiki/Plugins/WebPermissionsPlugin/Core.pm line 42

my $query = $session->{cgiQuery};

As of 5.0.1 it should be:

 my $query = $session->{request};

The plugin page now shows without an error.

Thank you Szymon for providing a proposed fix and for filing TWikibug:Item6655. I updated the plugin as follows to make it compatible with TWiki-5.0 as well as earlier releases:

my $query = $session->{request}; || $session->{cgiQuery};
