My site web is found on http://webimmo.tn

The mobile version is found on http://m.webimmo.tn .

The problem is when a visitor clicks on a link to a particular listing from the facebook page or an authre web sit on his mobile/smartphone, the link will not go to the particular listing but to the home page at http://m.webimmo.tn . Which is exasperating for the visitor.

So if the links has to point to: http://www.webimmo.tn/properties/ann...ergla-400.html and thus

http://www.m.webimmo.tn/properties/a...ergla-400.html
it just goes to the home page at http://m.webimmo.tn .

Am I missing something on a setting or something?
