Browser extensions or add-ons such as AdBlock can sometimes interfere with Philo. Successfully viewing Philo in a private or incognito browser window is indicative of this issue.
To test, repeat these steps for every extension or add-on:
- Disable the extension or add-on.
- Restart your browser.
- Open Philo.
Once you've found the culprit, consider changing its settings so it is disabled when watching Philo, or remove it entirely.
