I am using the standard wiki in moodle 1.8.3 +. This bug has also been replicated in the Demo Moodle site (username "teacher", password "demo").
On older versions of moodle, e.g. moodle 1.8, it was possible to export a wiki as a zip file, which could be saved on a users hard disk. The zip file contained an HTML version of the wiki. This was a great feature since it allowed students to keep an off-line 'portfolio' of their work.
This feature (along with other features of the Wiki module) now appears to be 'broken'. In order to export a wiki, the user clicks on the -- Choose Wiki Links -- pull-down menu, and selects 'Export pages'. Then teachers or admin can choose where to export the wiki: to a directory in the course files, or a Downloadable zip archive. Click here to see an image of this export page. Students can not choose, and are only able to download their wiki as a zip archive.
However, on clicking on the [Export] button, the following appears at the top of the page (this is just a sample):

I do hope that this can be fixed (see MDL-11816) since it appears the new wiki (NWiki) will not be a part of the standard Moodle release until the end of next year - version 2.0. Or, should I take the plunge and install Nwiki now?
