Can't Access In Progress Chapter

I tried to save a chapter I was working on as a draft, and now whenever I try accessing it, it says Gateway Error. The rest of the site works completely fine. Is there a way to salvage this chapter? I don't want to lose my progress.

Thanks

 

This is what happens when you drag and drop a picture into the chapter. You'll have to wait until someone who can remove the problematic picture sees your post.

 

I used the correct formatting, so i don't know what the issue is. Thank you though

 

The issue was the second image in that chapter. I have removed the image so it should work again.

(If I don't have a link or clue where to find the chapter, I can only guess where it might be.)

 

Thank You so much
