Hi @plose2009bx,
Good evening, and thanks for explaining your situation. Let’s go through this step by step.
The “Access blocked: Product Feed WordPress’s request is invalid” message usually appears when the browser is still linked to your previous Google Merchant authentication session. To connect the plugin to your new Merchant Account, please try the following:
- Go to Product Feed Manager → Google Merchant Settings.
- Click “Reset” to remove the old Google connection.
- Open your Google Account in a new browser tab and log out of all Google accounts.
- Then return to your WordPress dashboard and fill the fields again in respective of your new Merchant Account and then click “Submit”.
- This time, make sure to sign in with the email linked to your new Merchant account.
That should allow you to connect the new account properly.
Regarding your second point — even if you select “Delete plugin data on deletion,” WordPress sometimes keeps cached options which can be a reason.
Best regards,
