CANNOT FOCUS ELEMENT ERROR

[deepak11112]

well I see after adding the attachment (before its sent) on whatsapp it immediately closes the chrome and error pops out.
it was working fine few days back.

one more thing , is it possible to not get logged out every time when we send a file.
means , whatsapp login should be made only first time and we do not close that chrome tab , and after that whenever we send a file , sender must use preopened and logged in whatsapp tab .

Thanks in advance
