New install and looking at some of the features.
If I try the "Forgot my password" option, I get an email with a link in it:
http://dokuwiki/doku.php?do=resendpwd&pwauth=1dd988621f255b4cc1f2486811d1e8b
When I use it I get "Sorry, this auth code is not valid. Make sure you used the complete confirmation link."
In php.ini I simply have the smtp server pointing to our internal Exchange box, and the mail client is Outlook 2007.
Any ideas please?
