Thank you. What advice do you have helped, but not completely.
After adding the code, a new error.
Users attempt to come, writes a message that the username and password is not correct, although they are correct. and written by mistake "Oops! Something went wrong on the server. Please reload the page and try again."
But after reloading the page, the user has entered.
Here's a script because there is this error. how to fix it?
$(function() {
var iframe = $('#ourframe', parent.document.body);
iframe.height($(document.body).height());
});
if you remove the script, the error disappears.
