Side View Perspective

Sometimes when I switch to side view the graph won’t be there. And it also sometimes will show a cube looking angled from a straight top view. What is the problem here? How do you reset the views?

you probably aren’t in ortho mode

press the number pad 5 key to toggle between ortho mode and not

you will see the grid in top front right back bottom left views if you are in ortho mode, if you aren’t you will only see the xy plane grid, with the size setup in the backgroujnd properties panel thingy (which you can get to from the menu on the view’s header)
