I also change the values of the web/unsecure/base_url and web/secure/base_url fields in the core_config_data table to http://mydomain.com/store, but I'm still getting the same error.
How can I fix this problem?
It is something related to the htaccess file?
How can I display the PHP errors?
1. When i navigate to http://mydomain.com/store/some_url I'm being redirect to the root directory
2. The directory http://mydomain.com/store/ is under protected by Basic HTTP Authentication.
