Does not Load

Hi,

Thank you for your great Plugin!

unfortunately I couldn’t get it working! It only shows pupolar today and latest, when I click on week/month it stops working and only shows latest, not even showing loading gif!

I will appreciate if you could help me to resolve the issue.

Kind regards,
