Editor Hangs: How to reset?

tedyoung commented 3 weeks ago

Describe the bug Somehow I got into a state where the editor hangs and I have to kill the page (I was working on a sequence diagram, but the content is now lost). Now when I go to https://mermaid.live/edit, it shows an empty editor, but it still hangs. Is there a way to clear whatever is cached so I can use it again? If I open it in a private window, it's fine, so I'm guessing there's something in the history or cache that is preventing it from running properly.

Desktop (please complete the following information):

OS: MacOS
Browser: Brave

You should be able to clear data from chrome://settings/content/siteDetails?site=https%3A%2F%2Fmermaid.live We store the diagram history in localstorage.

It would be helpful if you can share the diagram code from localstorage, if you can get developer tools open in the page before you clear the data.

I think this is the one causing the problems, I was converting from a PlantUML format and was trying to fix line 9 (participant Ticketing) and it kept hanging for longer and longer until it would take minutes to respond.
