I've successfully edited home page of my Wiki, added some internal links like:
[Link name](link.md). Then I clicked one of that links and got a page with a 'Create this page' button. Clicked, edited the contents of this page, previewed but when I click 'Save' I get a 500 error.
Here's the code: 0eea24da08b1492395e6410b4b8185f5
