Level never loading

(Sorry, about creating another post on this topic but the others look like different problems)

Name: Vlevo
Level: Sarven Brawl

Error: it never loads the level.
the progress bar that comes up before you can click “Start Level” is tiny and stuck . . . it never gets to “inf.loop wanna comment out code?”

javascript console:

Try clearing your cache and refreshing a bit; that is this bug we have intermittently where some request doesn’t load right and the level loader gets all discombobulated. I haven’t been able to figure it out yet.

Clearing the cache did work.

I hate having to clear the whole cache, which part should I clear, “cookies and other site data” and/or “cached images and files”.

or is there some javascript console thing I could do?

Just cached images and files.
