ok i have tested on a 7.0.9 install unmodified --> vpsmanager.us
uploads work on firefox and chrome
tested on your instance:
there are problems with chrome for some reason there seems to be an iframe that is not being allowed to load.
where is this hosted? and are you able to see anything in the error logs?
i am attaching some screenshots from both sites on FF and Chrome
not that this fixes anything, but i can see there are differences in the source where that upload section should be showing up at. for some reason, FF chooses to load it just as it is and has no qualms, so i can only presume that the same issue chrome is having with the site IE is having with it as well.
your site in general seems to be having some issues with javascript and ajax it appears. as you can see the boonex news is not loading
the login link on the breadcrumb area does not work. the login button on the site does not work. so there are more issues than just the upload section that are going on here.
