Hi Matt,
The plugin configuration looks good to me.
The only other two times we've come across that particular error message it's been issues like an upgrade of the plugin with browsers or Django caching parts of the the old version.
See the two threads at

viewtopic.php?f=4&t=8318Did you replace an older or different version of the plugin with a new one?
Or if this is a fresh install, perhaps it's worth checking the versions of the prerequisites.
Is python-reportlab successfully installed in the same e.g. virtualenv which OMERO.web is using?
Best,
Kenny
