Only part that's really bugged are the drop-down menus, but the scuff is sufficient to make the tool near-unusable. But apparently the thing is just that some domain has expired or has been made private and there's an alternative addess. If you are able and willing to tinker with HTML, you can press F12 and locate:
- Code: Select all
https://code.getmdl.io/1.3.0/material.indigo-orange.min.css
then replace with
- Code: Select all
https://cdnjs.cloudflare.com/ajax/libs/material-design-lite/1.3.0/material.indigo-orange.min.css
The one pitfall that made this take way too long (for me personally) was that the relevant part was hidden under a close/collapse in the code editor. Thanks whoever made it work that way (could even be me, heck if I really know anything about how these things work.)
Ideally someone can somehow summon the OP to fix update the address on the back-end. Even if we figure out a fool-proof walk-through for this, it has to be done EVERY time the tab (or at least the browser) is closed and re-opened, and you want to use the tool again.
