OK, changing admin to Admin helped.

I also tried and changed Agnieszka.Skowronska to Agnieszka.skowronska and it also helped

I changed PiotrLuczak to Piotr.luczak and it also works.

So it looks like more than one capital letter breaks the system? But I have another used with several capital leters and it works...
