Unable to Add User to Journals

Hi Admin.
I just created a new journal in my institution OJS platform, but am not able to add new users to the journal from the administrative end. I think its probably due to some javascript fault… find below the error message from my browser console…

UserGridHandler.js:34 Uncaught TypeError: this.bindGlobal is not a function

I need help…
Thanks in advance

Can you access the server error log or can you ask the site manager to check the error log if something is logged there when that problem occurs?
