In my computer I can see the form perfect - explorer 11.0.70 and so is it in chrome;
In other - just for part of the forms, the display mode is not visible and other are working well.
When checking their permissions for the list and for the items specific - they have the same permissions as I have.
In the console, there is error: "unexpected ;", just in the forms that are not visible in specific computer (the error is not exist on other computer for the same form).
What could be the problem?
well, there wasn't. The problem was with explorer - there was a scrolling (a very big one).
I have used css for #s4-workspace and set it to be overflow:hidden.
