To determine which version of Squarespace you are using, follow these steps:

For Squarespace 7.0:

1. Login: Go to the Squarespace website (squarespace.com) and log in with your account credentials.
2. Access your site: From the dashboard, click on the website you wish to manage.
3. Check the Interface:
4. In the left-hand sidebar, look for the presence of the Home menu at the top. Squarespace 7.0 features a dashboard with a Home menu icon shaped like a house.
5. The style and structure of the editor will appear more streamlined as compared to the 7.1 version.
6. Templates: Navigate to the Design panel and then to Template. Squarespace 7.0 uses template families such as Brine, Bedford, or Pacific.

For Squarespace 7.1:

1. Login: Go to the Squarespace website (squarespace.com) and log in with your account credentials.
2. Access your site: From the dashboard, click on the website you wish to manage.
3. Check the Interface:
4. In the left-hand sidebar, you'll also see a Home menu at the top, but the overall layout of options in Squarespace 7.1 is slightly different and more modernized.
5. Squarespace 7.1 consolidates design settings, making it easier to access different style options in a centralized theme customizer.
6. Templates: Navigate to the Design panel and then to Templates. In Squarespace 7.1, there is no concept of template families; instead, it uses a universal set of templates that can be customized in a variety of ways.

Alternative Methods to Identify:

1. Look for Upgrade Notifications: If you see notifications to upgrade your site or templates, it's likely you are still on Squarespace 7.0.
2. Contact Support: If you're still unsure, you can contact Squarespace support. Provide them with your site URL, and they should be able to quickly determine which version you are using.
3. Account Settings: Check your account settings or plan details; sometimes these sections provide version information.

Things to Consider:

• Switching Versions: Be aware that switching from one version to another (e.g., 7.0 to 7.1) is not straightforward. This often requires rebuilding your site on the new version. Therefore, it's crucial to decide on the functionalities and design capabilities you prefer before committing to a version.
• Documentation and Tutorials: Make sure to consult Squarespace’s extensive documentation and tutorials, which are specially tailored for each version, to get the most out of your site-building experience.
