404 error

Simply explained , if I go see a Paige imdb , let's say Man of steel for example and then go watch the trailer or go see all the movie made by Henry Cavill after click on him in the list of actor , or every other action and then I go back to the previous page , every single time every single page come out the pop up the message error 404 The only solution to go around this problem is going back of another page and click for the destination page ... take in count that if still another imdb page instead of google one or the site where you use the link to that imdb page , you have to act before the page go to the 404 error one or block the loading of the page before that
