When enabling spectator mode on a server and starting to move, you are immediately kicked from the server with the message "Flying is not enabled on this server".

The half-spectating happens anytime you join a world in spectator mode.
Can be fixed by changing gamemodes.
Mods, please re-check. This is very obviously not a duplicate of MC-46408.
After join again I think you have a half spectator mode. You have fly, no infobars on bottom of the screen, but you can walk on the world.
