This happens if the Google Sheet has no header row or it was accidentally deleted. Go to the plugin’s Header Settings page, make a small change, and click Save. The plugin will automatically recreate the header row.

Google Sheets creates “Sheet 1” by default. Using the exact name “Sheet 1” for your sync sheet can sometimes cause conflicts or failures during initialization. We recommend using a unique, custom sheet name (e.g., “Contact_Form_Submissions”) in the plugin’s Sheet Name settings.

This error is caused by a GuzzleHttp conflict. Other plugins on your site (such as Dokan-Pro, Amelia Booking, WP Cloud Plugins, WP Media Addon, or Pixel Caffeine) may bundle older or conflicting versions of the Guzzle library, which conflicts with the Google API Client library used by WPSyncSheets.

Solution: Update all conflicting plugins to their latest versions. WPSyncSheets has released updates (v4.4.6 and later) to isolate its vendor libraries and resolve Guzzle conflicts. If the error continues, temporarily deactivate the conflicting plugin and contact WPSyncSheets support.

This error occurs when you have added “WPSyncSheets” in the form’s Actions After Submit settings but have left the Spreadsheet selection blank. Ensure you select a valid spreadsheet from the dropdown before saving.

This warning is shown because the OAuth app you created in your Google Developer account hasn’t been verified by Google. Since you created it and it’s running under your account, it is perfectly safe.

• To bypass this, click Advanced at the bottom-left of the warning screen, and then click Proceed to [Your App Name] (unsafe).

This happens when your Google Sheet does not contain enough blank columns to accommodate the mapped fields.

• Solution: Open your Google Sheet, manually add a few blank columns to the right side of the sheet, and try saving the settings in WordPress again.

If changes to header mapping are not reflected in Google Sheets, go to Header Settings in WordPress, add or remove a field (make a minor adjustment), and save again. This forces the plugin to regenerate and rebuild the header row in the Google Sheet.

Yes. WPSyncSheets supports multiple forms on a single page, each syncing to different spreadsheets or different sheets (tabs) within the same spreadsheet. If you encounter issues where the headers of one form are automatically pulled into another form, make sure you are using the latest version of the plugin where this issue has been resolved.

A 403 error during setup typically means missing authorization scopes or the Google app is still in “Testing” mode.

1. Re-generate the token and ensure you check all permission checkboxes on the Google OAuth consent screen.
2. Go to the Google Cloud Developer Console → OAuth consent screen.
3. Under “Publishing status”, click Publish App to move it from “Testing” to “Production”.

This error occurs because the Redirect URI defined in your Google Cloud Console credentials does not match the URL of your site’s WPSyncSheets settings page.

1. Copy the exact Redirect URI shown on your WPSyncSheets Settings page in WordPress.
2. Go to Google Cloud Console → APIs & Services → Credentials.
3. Click on your OAuth client ID.
4. Under Authorized redirect URIs, paste the copied URL. Ensure there are no extra spaces or trailing slashes.
5. Save the changes and try generating the authentication token again in WordPress.

This is a common issue when the API credentials are not properly saved. After generating and entering the Google authentication code in the settings, users often navigate away directly by clicking on other menu items without clicking the Save Settings button first.

• Always click the Save button immediately after pasting your authentication code before leaving the page.

No. Manually modifying, adding, or rearranging columns directly inside Google Sheets will cause a mismatch in the entry mapping and result in syncing errors or misplaced entry data.

• To edit or rearrange columns, go to the Header Settings tab inside the plugin in WordPress, drag and drop the fields to your desired layout, and click Save. This will automatically regenerate the columns in Google Sheets.

It is not recommended to clear the sheet manually.

Please use the Clear Spreadsheet button provided in the plugin.

If you absolutely must clear the sheet manually, make sure to keep the header row intact. The plugin depends on the header row for mapping and syncing.
