We were able to connect to the database server (which means your username and password is okay) but not able to select the inboundm_live2015 database.
inboundm_live201 have permission to use the inboundm_live2015 database?username_inboundm_live2015. Could that be the problem?If you don’t know how to set up a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.
