Apres installation message d'erreurs "Cookie paths cannot..." et " array_flip() expects parameter "

I had not noted the local sites which had this problem, but I have the impression that it disappeared. On the other hand, I installed Flexicontent on two other sites (also local) on which I had not done it and the problem is present. I installed them on my remote server and the problem disappeared.

You told me that it could be a "path problem related to Wamp or Joomla". So it would come from my WampServer. But what I don't understand is that if it comes from Wamp why does it work for the others? And what do you mean by "Wamp related installation path"?

I found out where the problem comes from! The folder names of my sites having several words, I wrote them with a space (for example: name of the site). But if I put a hyphen in the place of these spaces (site-name) the problem disappears.

ahhh good return => dont use it its not realy good in real server
thanks
