The log you posted is incomplete and not the required debug.log.

Read the FAQ at the top of the forum.

 

The actual error you show is a network protocol error.

This is usually caused by mods that were not test in multiplayer by the mod author or are mods for a different version of minecraft/forge with different network formats.

Since you say it only happens for people with OP, the issue is likely related to a mod that has custom commands?

 

Usually the only way the find the problem mod is to experiment with removing mods until the issue goes away.

Backup your world before removing mods.
