Shift Glitch <- Please help Asap (Urgent)

No console errors show yet people can't place blocks when in shift, only oped people can.
List of Plugins: http://pastebin.com/pJg4gqCX
Bukkit Version: craftbukkit_latest_development_build_1.7.9_r0.2_#3091.jar

Please help asap, urgent assistance needed.

 

drwill9570 Do they get a message when they try to place a block? Also, that's a lot of plugins to look through. I'm not sure why any would stop just placing while sneaking, so best I can offer is to remove all plugins and readd one by one until you find out which is causing the issue.

 

drwill9570 If you are still having this issue I would recommend removing one plugin at a time and see which on would be causing the problem. That is the best way I know of trying to isolate the issue.

 

Hmm, ok any other ideas?
