Hello @aworks621 and thanks for your question. You should be able to access and edit your website from your Square Dashboard. After logging into, from the menu on the left side, choose Online (you may need to scroll down to almost the bottom. Then choose Website > Edit site.
If this doesn't work for you, you can try this...
- log into Square
- clicked on your user name
- A drop down menu reveals Weebly website name
- Click on website name and go to Weebly website dashboard
- Click on Edit Website
