Sorry my graphs are not working

I try to read here to see if some solutions could be aply to me, but no, still not working.
I can access the live ones, but not the historic ones.

Hello,

The main advice (after purchasing a subscription) is to log out and log in again.
Please send a screenshot of the situation if doesn't help.

Thank you.

Hello! Can anyone tell me why the x-feeder customer service is not responding? I have written to them about 6 times in 2 months, but NO ANSWER! So how can you run a website? How can I trust them?! Can you help me, in such a situation, how can I dare to transfer money to them to purchase the monthly program? I await your respectful answers!
