Was it a specific scroll and did you have all the ingredients in the right amounts?

Cause I made one: Snape has created the Gate of Evil Scroll successfully!

Is this still happening?

Hey ! Are you still getting an error when trying to create scrolls?

Is that the only page you're having issues with? Have you tried clearing your browsers cookies/cache?

I tried to replicate, but can't on both Chrome and Firefox -- the page loads fine on both.
