1 I have an [IkiWiki site](http://ocikbapps.uzh.ch/gc3wiki), which works
2 fine, except for one page which I cannot edit with the CGI. Only this
3 single page is failing, editing every other works as expected.

23 # cat /etc/apache2/conf.d/limits.conf
24 LimitRequestFieldSize 65534
25 LimitRequestLine 65534
27 But I'm still getting the same error.
