hi anmys
there is a strange text object (beginning on line 671 in the code) on the non existing page "-1" with the strange position value YPOS="3080304.5". this is almost one kilometer below the four real document pages – i don't know your screen size, but…
after deleting this object the file opens again. you have to check, where this text (A tete-a-tete with nutritionist Shiksha Mishra unravells popular myths about fitness.) is missing.
