Specifically, if I enable it via Configure then reload InstalledPlugins, I get the error:
Can't locate object method "readTopicRaw" via package "TWiki"
I presume this would happen with any page, but InstalledPlugins
seemed to be a particular good one to reload after enabling a plugin.
This is in a freshly installed TWiki from the tgz, not via SVN, since I thought I'd "kick the tires" as suggested. I'm running mod_perl, in case this is relevant.
I marked this as urgent because it's packaged with RC1. Either it should be fixed or removed.
