Dear ali,

The issue about my car and login is solved.
About style of product. Please go to (/templates/sj_appstore_hitech/css/template.css)
find this code:

#content_listing a.modal {
overflow: hidden;
}

change to:

#content_listing a.modal {
overflow: hidden;
position: inherit;
}

Save and recheck.

Thanks & regards!
