Wynncraft Map Issues

For the past week, I've been having an issue with loading up the map- black screen with the "If you can see this message, there is likely a problem loading the Overviewer javascript components. Check the javascript console for error messages" error. Usually this appears when I have the map open for a long time and refresh it, and the easy solution is to close the tab and open the map in a new tab. For the past week, this has not fixed the issue. I have closed chrome and reopened it, tried using Firefox, and restarted my computer with no results. Any suggestions on how I might fix it?
