Help with error in Trail Head

I am getting the following error in "Customizing Compact Layouts" section of "Salesforce1 Mobile Basics" unit in Admin Beginner trail.

"Challenge Not yet complete... here's what's wrong:
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: MXFFWICC
Create and enable a compact layout."

Hi,

Sorry for this issue that you're encountering. Can you please double check that your Developer Edition Org does not have any namespaces setup in it?Trailhead does not support namespaced DE Orgs and so if you have a namespace registered for the DE Org, you'll need to sign up for a new one and complete this module there.

When trying trailhead, we encourage users to create new Dev orgs such that the previous config changes do not affect the trailhead challenge settings.

To login into trailhead you can use your old org but for activity(code and config) related changes you can use new org. In such a way all point will add in your old profile only.
Please check the below link for help.
