See how to access the Weebly editor from within the Account Control Center:
Hi. Sean here, and I’m going to tell you how to access the Weebly site editor for a domain that already is set up for Weebly hosting.
So once you’re logged in the Account Control Center scroll down on the left side to Add Ons, and then select Weebly Site Builder. From there you’ll get a list of all the domains that are set up for Weebly hosting.
Click on the domain name that you want to edit. Then on the right-hand side of the screen, the fifth button-down is Edit Weebly Site. Click on that and you are taken to the Weebly site editor.
