So there were these people on my server using x-ray hacks, and I was trying to ban them, but I didn't have op. I went to console to try to give myself op, but I only saw a blank console screen that looked like this: Even though I tried to type commands in the area that said 'Enter Command', it didn't work. This is really frustrating me, and I have no power over anything. Somebody please help.

The Captcha for Minehut is broken. If I get it correct, then absolutely NOTHING happens. I waited around 30 minutes after doing it like 10 times, and nothing happened. Now if I get it incorrect, then it just keeps counting down the times I get it incorrect. I'm not using a VPN or anything like that, so can somebody explain to me why this is happening? Thank you.
