Randomly moving? help!

A few days ago, my something weird started going on with my server. Everybody on my server, from time to time, would be randomly pushed continously making you unable to move. There are no lua errors, so i have no idea whats going on. If someone knows a fix to this, please help me!

Go over your addons, disable one by one until the problem is solved. By then you should know what addon is causing this.

Its anti player stuck addon. Thanks
