Server having Major issues

So on my friends server that I’m an developer on is having major issues. We don’t know really how to fix this at all. But when players phys gun props they can’t pick them up the props basically act like they’re welded to the world. I really have no idea as of right now what to do… I need help. Can anyone offer assistance? Or maybe some pointers to the issue?

What’s the gamemode? Are you using any prop protection? Can you give some more information?

The Gamemode is Darkrp. And we’re using the default plugin Falco’s Prop Protection. But as I said players can use the physics gun on the prop but they can’t move the prop. It just sticks to a fixed position in the world where ever they spawn it.
