"Properties disabled for now" Issue

While I was playing on my DarkRP server I spawned some props and tried removing them, however, I am getting a message in the corner of my screen saying “properties disabled for now”. I also cannot use my tool gun whatsoever. I have looked everywhere online and asked all my friends but they have no clue as to what’s causing it. I already tried reinstalling ULX from scratch to no avail. I have looked through all the admin options. I have no toolgun or group restrictions set up. Can anyone please help me?
