When calling the payment dialog - an empty window. What could be the problem?

Question

Classmates

After a while, this window appears:

I make the call as described in the documentation apiok.ru/wiki/display/api/FAPI.UI.showPayment+ru

FAPI.UI.showPayment("Яблоко", "Это очень вкусно!", 777, 1, null, null, "ok", "true");

Calling again does not work - only reloading the page.
How to "fight" with it?

Answer 1

Please send to [email protected] the id of the application and a description where you can try to pay in it.
Atypical problem, we'll see.
