after Upgrade sugar from 11.0.3 to 14.0.0 some issues on client side

HI All. 

I hope you can help me on this, I have done the upgrade with no errors but I have 2 issues. 

1. issue on Emails, when you select the email template it does not populate the email body, does any one knows why?
2. issue on doc merger when you try to merge it it does not pop up on the side bar, so we don't know if is working or not.
