I'm getting the error: "Failed to load datapacks, can't proceed with server load. You can either fix your datapacks or reset to vanilla with --safeMode" when i try to run my server, which worked properly yesterday But the oddest part is that i don't have any mods or datapacks on the server. I only have a client-side mod installed on my minecraft, not on the server. It would be fine if you could just teach me how to run the server in safe mode, if that would fix it. I don't need any datapacks in the future
