I have spent a long time building a store with Magento on my local development PC.
I find in web/unsecure/base_url
in magecore_config_data
database, if you search core_config_data
and see it is empty table, please search something like magecore_config_data
.
this mag that become in first part is asked of you when you install Magento as a prefix for Magento tables.
And one another point, I use wamp 2.2 and when I search databases in phpmyadmin that filtered only databases in that page, please change pages and search again.
