Dear Champ Camba, thank you for your answer!
your solution is working – buttons in the login form are changed their order!
That’s great!
And today I understood that I do not need this solution – at Login button there was a link “/register/” – I changed it to “/login/” – and my forms rendered in the right order!
So – I do appreciate your work and skills and your readiness to help!
Thank you very much!
