Done problem with shift button in my inventory

hello,
i have a problem when shift + left click an item in my inventory, the server just tells me '[MyM-DupeFix] canceled inventory action!'
i cannot move itmes from my inventory to a chest and the other way around (by shift+click)

 

Is this issue happening with any item or just a certain type of items? Usually the dupefix will stop certain actions with certain items, not all.

 

every items, even when i'm crafting something

 

Close out the pack and restart it.

 

already done it i even restart my pc
[doublepost=1546532764,1546526573][/doublepost]ok the server restarted and now the problem is gone (forever i hope) thanks

 

I'll go ahead and mark this thread as done the issue has been resolved. If the issue returns however, do not hesitate with letting us know by replying to this thread.

 

Common thing that happens. Only thing to fix it is a server restart
