Replying to [comment:6 Simon Charette]:
> If you're in the process of migrating from 3.7 to 3.8 you'll likely want
to subclass `FileBasedCache` and set its `pickle_protocol` to `4` and use
it as your backend during the transition period. When you've fully
migrated to Python 3.8 you can swap back to `FileBasedCache`.
I also was thinking about the cache, that is why I deleted everything in
the cache folder (/tmp/django/) but that didn't solve the error, it
happened again at the second load of the page.
I think having ability to set the pickle protocol version as an option
would benefit too.
