JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

Hello,

When i want to add a module to a trailmix i have this message : 
Firefox : JSON.parse: unexpected end of data at line 1 column 1 of the JSON data
Chrome : Unexpected end of JSON input
Explorer : Syntax error

I don't know if it's the good place for talking about this problem.
It's probably a problem on the web site code.

Thank you
Emilie

Try to logout once and then login again to check.I would suggest you reach trailhead@salesforce.com if this does not solve your issue.

Hi,
I'm faced to the same problem of Emilie when I add a trail or module to an existing trailmix especially.
I ask for the trailhead support.

Hi,
Trailmix has a bug which works only in English.

Please try the following procedure.
1. Set the language to "English" in the trailhead page(see the lower right).
2. Click the "trailmix"(see the naviguation) and "Create a Trailmix".
3. Add any trail,module or project.
4. After editing your trailmix, Set the language to prefered it.

Best Regards,
Masashi
