When I'm trying to install Whatsapp, it tells me to download it again. When I download it again, I receive a "There is a problem parsing the package" message. What should I do?
You receive this error because the Whatsapp installer is corrupted or not fully downloaded. In order to fix the error, I suggest you check your Internet connection, delete the installation package and download and install the application from an official source: Whatsapp website or Google Play Store.
