Wordpress 5.3.2 CiviCRM 5.21.0
I've recently upgraded to CiviCRM 5.21.0 successfully and everything was working fine.
Whilst tidying up the site, I inadvertently and stupidly changed the CiviCRM Resource URL to the site URL (not the full path) instead of [civicrm.root]/ I now cannot get into CiviCRM admin through Wordpress admin so am unable to change the resource URL back to how it was.
Does anyone know a way of resettting things through FTP or phpMyAdmin please?
The settings in civicrm-settings.php seem OK. I've tried reinstalling CiviCRM but still cannot get into Admin.
