[xwiki-users] error creating a page (XE 1.3.8295)

Hi, I'm trying to migrate an old XE 1.3.8295 farm to a newer server and previously solve some know issues. When a try to create certain documents in of the virtual wikis I get errors like this... http://ftp.ebiotic.net/fromMire/wokflow20100909Error.txt I've get, and Sergiu had solved, some similar errors in an update from 1.3M2, but I don't understand in this case why I was able to create WorkFlow/20100908 and WorkFlow/20100910 pages but WorkFlow/20100909 fails with this error message. Any idea will be welcome! Thank you so much! Greetings, Ricardo -- Ricardo Rodríguez CTO eBioTIC. Life Sciences, Data Modeling and Information Management Systems
