While I trying to update the secure URL and unsecured URL on my new Magento installation. It shows above error but the website is working fine.
Even my memory limit is 1024M and PHP version: 5.6
What I need to proceed further to change my URL from example.com to test.com
not willing to reinstall fresh Magento.
Help me, guys.!!!!
Since you're using PhpMyAdmin (because the screenshot) can you check the list of tables for that database?
Maybe you can run this query:
select * from information_schema.TABLES where TABLE_SCHEMA = 'your_database_name' and TABLE_NAME = 'core_config_data'
