If you're seeing this error while trying to create a table from a Google Sheet, it typically means there's an issue with either the type of link you're using or the plugin version.
Here’s how to troubleshoot and fix it:
✅ 1. Make sure you're using wpDataTables version 7.2 or higher
Google made changes to how third-party applications access Sheets. As a result, wpDataTables version 7.1 and earlier may not work properly with public links.
This issue has been resolved in version 7.2, so please update the plugin to the latest version.
🔗 2. Check the type of link you're using
There are two types of Google Sheet links:
🔹 “Publish to Web” Link
(Usually starts with https://docs.google.com/spreadsheets/d/e/2PACX...)

This is the recommended method for public Sheets.
Paste this link directly into wpDataTables when creating the table.
✅ No API key is required.

🔹 Browser Address Bar Link
(Typically ends with /edit#gid=0 — copied from the top of the browser)

If you're using this link, you'll need to:
Connect a Google Sheets API service account in wpDataTables settings.
Share the sheet with the service account email so it has access.
