Is OpenProject abandoned?

I'm trying to find a local project management system that I can share with others outside my company and I found OpenProject was repeatedly recommended. However, every attempt at installing ends up in errors. Their own community forums are down with website errors. I have a feeling this is abandoned software.

If that's the case, is there anything anyone can recommend with the customization of Monday or Asana that I can self host? I have a zero budget as anything that costs a dollar will be cut at will by my employer, and usually without a moment's notice.
