Reset 3D Views

Hello

I have a small problem with my 3D views.

When I open a room they are all upside down and if I click on front view, left, right,... they are crooked.

Does anyone know how to reset the parmis of views? (Turning around the stage floor is disabled)

Thank you very much in advance

You press the spacebar to open the "orientation" menu

you click on the 4th icon of the menu bar which is called "restore standard views"

Thank you very much
