My Minecraft Dynmap plugin has not been working for a few hours, every time I try to execute a command it only comes: an internal error occurred? Unfortunately, reinstalling did nothing
Have a look in the server.log file, what it says about Dynmap. There may be the mistake. Maybe something is wrong in the config.
When you reinstalled, did you delete the config file from dynmap before?
Here is a guide to the configuration:

Yes, I deleted everything, I installed a newer version
