Troubleshoot the Eventually panel in Squarespace

This is expected, not a failure. The Eventually panel activates only in Squarespace admin or edit mode; it does nothing on the public-facing site.

The panel script is missing or carrying an invalid panel key, so it stops before it can connect. Replace the script in Squarespace Code Injection with the key-based script from Install and connect the Eventually panel in Squarespace. If the message names your team, confirm you're a member of that site's team (see Roles and permissions).

The script in Code Injection uses the old ?sid= format, which the panel now ignores. Replace it with the key-based install script from Install and connect the Eventually panel in Squarespace.

You're on the site's team, but your Eventually account setup isn't finished yet, and the panel connection waits for that. Click Finish setting up your account in the popup: it opens the welcome flow for that team in a new tab. Finish setup there, then click I've finished, try again in the popup to reload the connection. If your team access returns to the pending-setup state later, any active panel session is rejected and the panel returns to the connection flow.

The popup must be opened from the panel in Squarespace admin, not from a public page or a direct link. Open the panel in Squarespace admin and launch the popup from there.

The page requesting the panel isn't the connected site or one of its approved Squarespace built-in domains. Open the panel from the connected site or its approved Squarespace built-in domain.

Panel connections last 12 hours and don't auto-renew. After they expire, the panel clears its cached session and returns to the connection flow ("Connect to Eventually" and "Sign in to connect →") rather than stopping. Reconnect by signing in again.

Removing a user from the site team invalidates that user's panel access immediately, even mid-session, and the panel returns to the connection flow. To use the panel again, have the user added back to the site team and sign in again.

The panel failed to load your events. Reopen the panel to try again.

Panel popup failures show "Please sign in to Eventually again.", "Could not create a panel session.", or "Could not reach Eventually. Try again." Sign in to Eventually again, then reopen the panel and try again.

Excessive requests can hit a temporary per-user limit, and the popup may show "Could not create a panel session." Wait briefly, then retry.

Changing or resetting your password invalidates the panel session immediately, and the panel clears its old session and returns to the connection flow. Sign in again to reconnect.
