I am using PythonAnywhere for my site http://tripshare.pythonanywhere.com/TripShare/. However, every 2 days or more the webpage is not correctly displayed (only one trip can be found) and I have to drop my database and run the population script. This webpage is mostly for display purposes and I still get around 300 visits per day which are clearly from crawler bots. Do you have any idea why this is happening and how to fix it?
