Clearing cache does not help

Did you fully clear your entire cache?

I cleared last hour , do I need to clear all time cache?

Cleared All, Still nothing

Did you fully clear the cache immediately after having this issue? If not, then clearing the cache cannot help fix it.

Fully cleared? And restarted the browser? You had to log back into freeCodeCamp?

Ok I’ll Inform you after logging in again

Did everything, nothing helped. Now I logged in with a different browser, it worked. I don’t know what the issue was but thanks!

I suspect you aren’t fully clearing everything out of your browser cache. Some browsers make it confusing to actually fully clear the cache and by default only partially clear the cache.
