Can't move any axis but the Z axis

So I’m currently using 2.79 as it is easier than 2.8, and I’ve been having an issue with the rotate tool. Wherever I click, the part just rotates the z axis. Even if I click the red or green lines, it will rotate the z axis. I am only having an issue with the rotate tool, the other tools work just fine. I am relatively new to blender, and I was just curious if there is anything I can do to fix this issue.

does it happen with all the object you select? Maybe you’ve locked the X and Y rotation for this object?

i checked and everything is unlocked.

could you please share just one object of your file?
