Help! Final render in blender is white.

I don’t know why this happened.When in viewport render, everything looks normal,but when i hit F12 to render, the final render turns white!Here’s the file: https://www.dropbox.com/s/zd1ggwcwqozsxtu/volcano.blend?dl=0.

Help pls. Thx in advance!

For me, both renders are the same and not white. Can you show pictures of both renders on your side ?

You have a fluid simulation that is enabled in the viewport but you have not enabled it for rendering so it is just showing the domain cube


and that is the probem!Damn i feel like an idiot!Anyway thx guys!

You’re not an idiot. It happens to everyone, it’s the process of learning. And actually I failed to see the solution of Richard Marklew, good thing he was there.
