Error message when try to preview

I recently changed a couple of text from my site. When I click the preview button, start getting this error and I don’t know how to fix it. Please help!

Try restarting RapidWeaver (and your Mac). Hopefully that will resolve the issue for you!

Thank you. I just did, and the error is gone. I think the reason is this; I suddenly canceled the publishing and this caused this problem. Just like you said, restart fixed the issue. But I little scared :anxious_face_with_sweat:

Edit: My thought is wrong, it is not related to canceling Publish. Now I made changes on another page and I got the same error. Is there an issue with my file?
