After the slowness of the PHP upgrade script and the disappearance of the URL Wildcard translation (these problems are corrected in the future 3.10.1 release), eZ Publish 3.10.0 gives me another problem when I try to upgrade a 3.9.0 site. Running the updateniceurls.php PHP script transforms the nice URL aliases into numbers. Another developer seemed to have the same problem in the forum, but no solution was provided…

In fact, for this site I configured one var directory for each siteaccess (I don't know why…), so when I cleared the cache using ezcache.php script only the cache of the default siteaccess was really cleared and obviously I specified the one with a dirty cache to run upgrade scripts ! That's why updateniceurls.php didn't find the URL transformation commands and made strange things…

We can sometimes read "Remember to clear the cache", now I would say "Remember to clear the cache for all siteaccesses" :-)
