Upgrade to (with clean urls)


I am writing here because I am wondering if my new and fresh clean urls (with mod rewrite) may create a problem while upgrading OJS. I am now trying the procedure to upgrade from to, but I am getting an error 404 page when I access the page in order to upgrade the database.
Is there anything already known about this?
Best regards,
