If you’re having issues with Dynmap, like flashing or if something is not showing properly, this should help you. Keep in mind, if the map is not updating very quickly, to mirror changes in the world, this is normal, rendering takes a moment. If the changes don’t show up for more than a day, you can contact an administrator.

Try the steps bellow, until it starts working properly again:

• Try refreshing the Dynmap by pressing ctrl + F5
• Press ctrl + shift + c, go to network tab, check Disable cache, try ctrl + F5, uncheck Disable cache
• Clear your cookies and cache on your browser and try the previous step again
• If it still doesn’t work, contact an administrator
