this definitely solved my problem of the admin menu not appearing after a fresh install, my file permissions were already changed for the specifed files, but i hadn’t added the edited head.php file
chmod 755 the /installpath/js/ folder, and folders within.
then inside /installpath/js/lib/ CHMOD 644 the javascript files there.
Not sure if the head.php fix is needed or not, but now my admin menu is showing.
thanks for the post...my folders were already chmodded correctly but my index.php file inside the js folder wasnt so now it is and now the menu works. thanks again
