I am using Moodle 1.8. When I try to update from Wiki to NWIKI, an error occurrs: (see the image below) Continue doesn't appear and i cant return to home page.
Please help me!
I got the same problem, when I changed from ewiki to nwiki on my moodle 1.7 !!! My admin account is blocked by this procedure / messages! How can I return to my admin-Account???
What can I do to get a stable wiki-environment without data-loss if possible??
Its urgent, because it's our productive-environment!!
I tested the same procedure on my test-installation last week without any problems!
Thanks in advance, Urs
Not anyone here with a workaround for this Problem??
Ok, works again!
I checked the wiki-tables and mentioned theat they're all as before. After moving back the old ewiki mod-files everything worked fine as it was!
But: I really want to change to nwiki! 
Any other iedeas?
