Can't craft

Hi there,so I was playing on my server last night and I got this problem:

I can't craft anything,ANYTHING...Not even in the inv. craft and not in the crafting table..

Can someone help me?

-I did try looking up on youtube but all I found is a creepy guy saying "Can't make crafting table!?"

1 more thing:When I try to craft something,like wooden planks etc.. It just shows up on a split second and dissapears..

If I do manage to reach it,It dissapears again.

Here you go!

Btw,I can craft in singleplayer.

Hi there,I just reset my server and everything is working fine!

Thank you for helping.
