Customer account (User control panel): "Edit your account information"

Hello,
I somehow deactivated the "Edit your account information" part of the User control panel (only two parts left: addresses and orders) and now I don't find how to activate again. Can anybody help?
Thank You.

Thank you very much - that was it!

Can I place a next question here?
Now in the account information page the two buttons do not work. If I press Send or Cancel Button, nothing seems to happen (nothing is saved and the page is not aborted to go back to the customer account page - like on the other sub-pages of the account ( see my image). There is no Back button or so. (For info: I use the "Haven" template of favthemes.com).

Best regards.

Hi Jotka, did you solve the problem? I also want to edit the buttons - but where?

Hi Nicolas - yes you're right! Sorry.

Hi ,
The same issue I have as well. The buttons on edit profile page act strange: the confirm button do his job, the edited info is saved, but it do not redirect after saving back to user's control panel, as it should (my opinion), after saving the user stays in edit profile page. The button cancel just reloads the same page.
I read many topics about this issue and know that it is not hika support field.

how ever I found hikashop user account plugin (it comes with the full package instalation) ---> I thought this plugin was created exactly for this issue and it will solve this problem, but looks like the issue is somewhere else or Im doing something wrong with this plugin. (please see attached)

Redirect back -> yes
Force menu -> (menu ID)


Appreciate for any help here

Thank you Jerome.
