Thank you for your reponse Roblagatta
I think I solved the problem by modifing the ecp-page-template.php and ecp-single-template.php and adding some other <div>
I still don’t understand why there is no problem with the local site and one with the web one. But with this modifications, it looks good.
The first problem I identified was that the web site lost a <div> so the footer where in the <div id=”page” > which is center with a special dimension, so I had to add a </div> before the get_footer(); and then I add <div id=”content” …> to the different files to have my background back.
Strange problem, but I think it’s solved.
Thank you also, for your reactivity
and again, very good plugin !
