How to Delete Old Analytics Data & Start a Fresh Import

Hello,

Thank you for your patience.

For troubleshooting, please follow these steps to regenerate the token on your site:

1. Please delete RankMath’s app from here:

https://myaccount.google.com/permissions

2. Reconnect the account inside Rank Math by clicking here and ensure that you approve all the permission notices that show up:
WP Dashboard >> Rank Math >> General Settings >> Analytics tab, and click the Reconnect link

Allow all the permissions on the next screen.

3. Let the process complete, which might take around 30 minutes to fetch the data.

If the issue persists, please follow the steps below to create a troubleshooting log so that we can check the issue further:

Step #1.
First, add the following filter to your website:

add_filter( 'rank_math/analytics/log_response', '__return_true' );

Here is a guide you can follow to add the filter:

Step #2.
After adding the filter, please run the pending Scheduled Action from your WordPress Dashboard > Tools > Scheduled Actions > Pending:

If in your case, you do not see the Scheduled Actions menu, then you can try visiting the following URL:

https://yourdomain.com/wp-admin/tools.php?page=action-scheduler&status=pending

Ensure that you replace yourdomain.com with your own domain in the above link.

Step #3.
When some actions have completed running, please check the Analytics log under /wp-content/uploads/rank-math and share that with us.

You can use a tool like Dropbox/Pastebin for debug log files and share the generated links here.

Looking forward to helping you.
