Thanks for catching that! I couldn't find anything from my logs, that was frustrating. The frontend of Peerdiem is served from www.peerdiem.com while the backend uses www.api.peerdiem.com. It seems that a strict tuning of the AdBlocker might prevent requests to a subdomains. I will put up an explanatory text on the homepage for those encountering the same issue. Thanks again!

Yep, Firefox with ad blocker here too. That seems to be the issue
