Hi @KateGonchaya19,
That’s a difficult one. Is it a picture of a Yeti in a blizzard? 
But, seriously, what kind of wrong pictures (and which course)?
I have a PRO account.
But I can’t see best series - empty data.
And after lesson i can’t see correct option “difficult words”. Three windows - difficult words, repeat and fast repeat place wrong.
Hi @KateGonchaya19,
That’s better. I can see your screenshots now. It was only a white space before. 
By “best series”, do you mean the “Best streak” counter that appears on your dashboard? Mine looks like this - with my data entered in red type:
After a lesson/test - where wrong answers have been given - the orange “difficult words” button should show a number, like this:
If there are no difficult words (yet), that button will show grey colour (with a zero).
Let’s ask @MemriseMatty or @Joshua from the Memrise Team to take a look at what’s happening in your account.
Good luck!
@KateGonchaya19, it looks to me like some of the JavaScript on the page isn’t working. If your English is good enough to use the site in English, can you give that a try? Obviously that’s not ideal, but it might work until Memrise fixes the bug 
thank you!
it’s work now

Great!
Hopefully someone from the Memrise team (@Joshua or @MemriseMatty?) can take a look at this, anyway, though. I know @alanh already tagged them, but I’m tagging them again.
