Try different browser. Try incognito mode. Clean cache, cookies.

I get the similar malfunction using old Firefox trying to access PM site since last week 😞 so have to use Chrome or Edge.

@damk   Unfortunately, PM website seems to be prone to glitches on a regular basis lately. 

Just wait an hour or so and make sure to clear browser cache/cookies using privacy/incognito mode or even another browser before retrying.
