Stak

Install guides

Pick the plugin you bought. Every Stak plugin installs the same way — two blocks of code, one page, one form field — but the details differ enough that following the wrong guide will cost you an afternoon.

Not sure which one you bought? Your receipt names it, and so does the heading at the top of your downloaded file.

What is true for all of them

Your Squarespace plan has to allow custom code

Business, or one of the Commerce plans. Squarespace blocks code injection on Personal and Basic, so nothing of this kind can run there at all. Check under Settings, then Billing, if you are not sure.

You paste two blocks, and they are not interchangeable

BlockWhere it goes
Block 1Code Injection, the Footer box. Runs site-wide.
Block 2A Code Block on the one page that shows the list.

Swapping them is the most common install problem, and the symptom is that nothing happens at all. Each block says which one it is in its first three lines.

Test on your live site, not in the editor

Code injection behaves differently inside the Squarespace editor and often does not run there. A plugin that looks broken in the editor is usually working fine on the live page.

Squarespace also redirects your own domain to the admin panel while you are logged in, so even getting to your live site is less obvious than it sounds. Each guide covers how.

You have 30 days to change your mind about the settings

Inside that window you can reopen the customiser and adjust anything — icon, colour, wording, placement — and download again. After it, the settings are fixed, but the link keeps working: come back any time to re-download your code, including compatibility updates after a Squarespace change.
