Additional comments

Happens with the posts that return "null" in the edited field of the json.

Quick fix

Not a good looking fix but it works for those who want to fix it asap.

In main.py l.205

                with open(json_path, 'r') as f:
                    data = json.loads(f.read())
                # Check if remote edit is null. If it is, logs that we cannot verify the date.
                if data['edited'] is None:
                    logger.info("Cannot verify if post has been updated.")
                    return False
               # Check if local edit is null while the remote isn't. It just skips the next part checking the dates.
                elif self.current_post['edited'] is None:
                    logger.info("Updating post.")
                else:
                    current_post_date = datetime.datetime.strptime(self.current_post['edited'], r'%a, %d %b %Y %H:%M:%S %Z')
                    old_post_date = datetime.datetime.strptime(data['edited'], r'%a, %d %b %Y %H:%M:%S %Z')
                    if old_post_date > current_post_date:
                        logger.info("Skipping Post: Post is up to date")
                        return False

Will add a fix by tonight didn't know the edited value could store null.
