I have some trouble with wiki module in moodle 1.5.3+ (2005060230)
First of all, I have trouble editing existing pages. You can check it on the wiki at
Clicking on edit tab of any page, it navigates to:
which is interpreted as editing a new page called editPageName (i.e., if you aim to edit WikiFormato, you end on a new page called editWikiFormato). I have slash arguments disabled in my site, since my hosting provider has it disabled in apache and does not allow overrides.
(EDIT: I've just seen a bug in wiki has been corrected in the last days. I'll check that).
Second problem deals with international chars. I have no trouble with putting wiki links with accented chars in moodle 1.4.x in my local server, but the exported wiki does not work in moodle 1.5.x in my hosting provider. I think it deals with url charset, but I can't find a way to make moodle unaccent every wiki link (i.e. I know wikipages with accented names will be inaccesible, but other users of this wiki could forget about it).
