Recently I opened Whatsapp and realized that all of a sudden every chat messages have disappeared… They are very important to me, I need help on how to recover my lost messages. I have tried backing up from the chat settings however it responded "Unable to backup messages". I am frustrated as of what I should do. And, even if my messages are 'out of sight', are they still stored in Whatsapp's database? Please help me! :[ I want to cry.
