Experiencing a strange situation where the database upgrade url worked perfectly for a testing site but not for the live site.
I successfully tested the upgrade with a cloned staging site without a hitch in the upgrade process.
By following the CiviCRM Wordpress upgrade guide: https://docs.civicrm.org/sysadmin/en/latest/upgrade/wordpress/
However, as soon as I attempted on the main site the updgrade database url loops back to the WP login page.
- Login as administrator for wordpress site
- Paste upgrade database url into browser http://islandnaturetrust.ca/wp-admin/admin.php?page=CiviCRM&q=civicrm/upgrade&reset=1
- Page redirects to WP login page with no errors.
- Login once more
- Paste URL
- Returned back to WP login page
I've checked the CiviCRM debug log but no errors reported.
UPDATE: Upgrading from 5.25 to 5.34
