Ok here is a step by step of what I did (sry maybe I should have posted earlier).
Step 1: You can see in this pic, 1) the size is set at 5.6x9.2cm. 2) the rulers on the side of page also verify this. 3) all margins are set to zero. NB: this is the file I used to make business cards, and there was no problem with it.
Step 2: Create new profile and change measurments
So here you can see I making a new profile if 9.2 x 5.6 now.
Step 3:
Next I pressed "ok" on the "custom paper sizes" window. this is the result right after that.
As you can see the "Setting " has changed to 9.2 x 5.6.
Step 4:
I then pressed "OK" on the page setup, and then pages automaticallt changes it back to A4 size. (didnt take pic). I then went to "file>Page setup" and then took the following pic.
Can someone try this and see if they have the same problem? (the goal is to create a retangular business card with long side on the bottom). Really cannot see what I am doing wrong. Thanks all for the input so far, and thanks in advance!!!
