Hi, under a project site, there is the icon “icon-align-justify”. This icon has the link: /portfolio-listing.html wich should opens the projects overview page. BUT there comes the 404 error page. Even on your DEMO page.
I opens the single-project.php file and changed on line 27 the link into “/project” instead of “portfolio-listing.html” But nothing happens.. it still opens the “portfolio-listing.html” page and 404 appears.
