Hello, 

There is an issue with the ios display of project, on a normal screen there is no way to close the overlay of a project to go back to the grid, the cross icon (<div class="cbp-popup-close" title="Close (Esc arrow key)" data-action="close"></div>) is not there anymore.

in the css file style.css on line 3788

../sites/all/themes/md_ariva/images/singlepage-close.png is not a valid url

i changed the line to

background: url("images/singlepage-close.png") no-repeat scroll center center transparent !important;

works fine now
