Render won't save to file

I’m having an issue where when I render something, it won’t save to the designated location. It worked earlier, as I have many rendered images of some earlier things, but it stopped working at some point, perhaps when I changed the resolution.

Here are my render settings:

Are you trying to save a rendered image ? If so, read the tooltip for the render output location. You will read that this is the location for rendered animations (including image sequences).

For still images use the Image / Save as Image menu in the render window after rendering or F3

Thank you. This solved my problem.

If you want, you can set both the Start Frame and the End Frame to any single frame you want and Blender will save automatically the image… if you ask it to render an animation, of course.
