Thanks Klimashevich for help.
But question to ARTIO Company:
What will you do with that problem? I don't only mean improving the code, which is obvious, but with situation like this: last year was almost the same problem, it was skipping a year on the 1st of January. You told all your customers, that latest version will fix it. So I bought one more subscription, upload latest version, everything was working fine until yesterday. And now my client cannot make any reservations until 4th. Do you know how we are looking in the eyes of our clients? They paid for the same thing again (?!) which crashed their site for few days?! Dozens of sites with Artio Booking - Lasertag in Germany, Escape Room in Poland, dozens of admins had the same problems - 100 calls from their clients asking "WTF?!". I guess you'll fix the code soon, and it will work good... until next New Years Eve..?
And by the way... when all of us had the same problem, you did/write nothing. Just one of your Customers wrote the code, and explain when it will work. Great job!
