With some items, "K2 Facebook share button" share an URL like this : www.nosyweb.fr/.../item/-.html

For example :
www.nosyweb.fr/tutoriels-libres/item/258-bien-debuter-la-creation-dun-site-web-en-3-lecons.html

But here, it's ok :
www.nosyweb.fr/actualite-creation-internet/les-dernieres-news/item/234-nouvelle-release-215-pour-joomfish.html

Problems disapears when I disable URL rewriting.

Somebody knows this bug ?

Thanks a lot.

Re,

It's because of my URL Rewriting suffix .html, if I remove it, everythings is ok but I haven't found any solutions to repare this problem.
