Thank you!

Yes I am sure the key is entered and I get an answer - but it shows everywhere zero in hashrate, shares, balance and working miners :-( I had 0.09 on balance from the last found block and many shares from this last block on.

Today I tried again to see "My Stats" and I get the form - everything shows zero :-(

Although 2 miners are working.

Hi & thank you! It is 4BDgvyN6Vn3TTa8zGQKn87A4wzqUPqNF4i5iib9YF83t69e4G4dEn3c3dhcDqUWE9NMYP9yeafr3eMkGNe1Yx8Et1W7aUFS

Yes :-)

But unfortunately I cannot get the statistics for my wallet. After entering the wallet address I see the "Loading animation" and then back the text input with the wallet address inside.

Clearing the cache did not help but deleting cookies :-)

Strange - in Chromium I get a 404 error and in Firefox only a blank page.
