I am not a Magento programmer -
Before The admin login was not working at all.
After reading the forums, I deleted the records for base_url from the core_config_data table.
Now I can login BUT when I logout and in order for me to log back in, I have to clear the cache and session folders AND also clear the browser cookie data EVERY TIME.
Why would that happen!??
Also, I see the following message on admin -
{{base_url}} is not recommended to use in a production environment to declare the Base Unsecure URL / Base Secure URL. It is highly recommended to change this value in your Magento configuration.
