No cross in pop – up

Replies: 1

Hi,
I have a problem with my pop – up. It doesn’t show the cross to close it. It exists but It is not visible ( I mean I can close on the computer clicking on the upper right corner of pop -up, but there is no “X”).
On the phone, there is no “X” either I can’t close with an invisible button like on the computer.
What should I do? Had anyone same problem?

Thanks in advance
