Light Modifier server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.6). You can switch loaders with one click in the panel.

Server lagging with Light Modifier – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Light Modifier consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
