Recently I upgraded a WordPress 3.0 installation to 3.8 and the drag and drop functionality stopped working.
I noticed two JavaScript errors on the page in the load-scripts.php
file indicating an ILLEGAL token . The error I got from the chrome console is this:
Uncaught SyntaxError: Unexpected identifier load-scripts.php? c = 1 & load% 5B% 5D = hoverIntent, common, admin-bar, jquery-ui-core ... pabl e, admin-widgets, svg-painter, heartbeat, wp-auth-check, thickbox & ver = 3.8: 2
I have already disabled all the plugins and other steps indicated in a post in the forum WordPress , but it still did not solve the problem.
