If you see a blank screen when loading Photo Ephemeris Web, there are a number of browser settings to check.
- Check your browser version: ensure you're using an up-to-date version - see Browse Happy for options
- Ensure Cookies are allowed - see Photo Ephemeris Web requires login every time
- Whitelist the site with any Ad Blocker or Content Blocker you are using, or relax the restrictions in line with your preferences - see Cookie banner not displayed
- Finally, the site will not work with Google Translate or similar automatic translation services - please disable this function to use the app (we have additional languages in the works)
If you are unable to login, or if the map does not appear but instead says "Waiting for map configuration" after sign in, try signing out, and then reload the page twice - this should clear any stale data that might be causing this. If it does not, then try deleting/clearing the site information from your browser (instructions for Chrome, Firefox, Safari, MS Edge).
