回答1:
execute the following query in mysql (via phpmyadmin or command line) to see what the current values are:
select * from core_config_data where path like '%base%url%';
and then update accordingly
update core_config_data set value = 'http://myhostname/js/' where path = 'web/unsecure/base_js_url';
