Magento – I change the admin URL to a custom URL and I cannot access the store admin anymore.

magento2.2.6url

I change my admin URL to a custom URL and I cannot access my store admin anymore.

How can I revert the change that I made?

Try this:

Go to your database and find the table core_config_data

Find the path column web/unsecure/base_url and web/secure/base_url

Then edit the value column of those rows. Remember to use / at the ending of the URLs or it won't work.

The reason why that worked, is because Magento internals will use the current store id on Mage::getModel('catalog/product').

You could have used Mage::getModel('catalog/product')->setStoreId('STORE_ID');

Try it like this:

$product->setStoreId(2)->getUrlInStore();
