If auto_header option fails, you can still load your chat manually specifying the hformat. In the example below,
we have that the hformat='%d.%m.%y, %H:%M - %name:'.
>>> from whatstk.whatsapp.objects import WhatsAppChat
>>> from whatstk.data import whatsapp_urls
>>> chat = WhatsAppChat.from_source(filepath=whatsapp_urls.POKEMON, hformat='%d.%m.%y, %H:%M - %name:')
>>> chat.df.head(5)
date username message
