After reading through your errors this doesn’t seem to be an issue with AMP itself; has the server ever worked for you or is this a new set up? Have you made sure in configuration under Java you have the right version selected and path defined as Mike mentioned?
I don’t know if I did some wrong at creation, but I tried 2 times and had the same errors.
Is there a tutorial to add mods with forge to an instance from 0? I was searching but the version of the panel was older than the current one…
I have mods that have biomes, so I would like to add them as soon as the world is generated.
