I can't spawn items from the stupid f1 menu

I'm about to go crazy, help me, I recently opened a server. I can open noclip, but I can never spawn items for myself from the f1 menu. I have admin authority, I registered, I have a zero plugin, I installed the plugin, it still didn't work, I'm going crazy, why is this happening? 4. I'm rebuilding the server, help me.
