Errors on docu zone

Hi all,

°°°°°°° Document creation °°°°°°

I had try to create page on : 
https://lenya.zones.apache.org/cms/docu/authoring/docu20.html

But I have this error displaying on top of page creation form :

     * Exception during commit or rollback: 
org.apache.cocoon.components.search.IndexException: message: (see 
logfiles for details)


But in fact... page is created !
Not so nice thought. Idea for fix that ?

°°°°°°°° Document modification °°°°°°°°

It's soooooo long !

I'm in my father home, with a little connexion... but I think there is a 
problem...

Any one can confirm ?

Thanks,
Have a good we.
