My portfolio can't be seen.

Scroll to the bottom of your contributor dashboard page and click “Change Region” on the far-left bottom corner of the page. You can select from various countries displayed, most of which will allow your content to be displayed.

Indonesia is a blocked region. 

Change the country code in your browser’s address bar from /in/  to an unblocked region like Canada /ca/, United Kingdom /uk/ or France /fr/. 

Hope that helps.
