Hi there Cédric!
I am publishing my friend's site, and now there are a bunch of little things that don't seem to work now on the server, and worked in my local folder for some reason.
I put a slideshow in the homepage, and another two in the contact tab. the code is pretty much the same, and I followed the steps you gave in the ebook. Now, the ones in the contact page work perfectly, but the one in the home page is just not there...
I'm testing in chrome and firefox
the site is http://www.therapydoneright.com
