What is the next step after received acceptance from the Editor I received an acceptance from the Editor by email, but when I checked the status of my manuscript in the journal website it is "Editor Decision", even after week of receiving the email.

what does that mean? and should I talk to the Editor?
If the editor emails you an acceptance, the paper is accepted.  Don't worry about the website not updating.

The acceptance email should contain instructions as to what you have to do next: presumably, make any changes suggested by the reviewers and submit a final version of your manuscript.  If it doesn't, wait another week or so to see if you get an email that does have the instructions (this might be sent automatically by the management system when the editor updates it). If not, email the editor then.
