Title: Error Establishing Database Connection Last modified: August 19, 2016 --- # Error Establishing Database Connection * [johnedwardlow](https://wordpress.org/support/users/johnedwardlow/) * (@johnedwardlow) * [17 years ago](https://wordpress.org/support/topic/error-establishing-database-connection-17/) * Hi. I am new to this and sort of dumb. * I am getting the following error message: * This either means that the username and password information in your wp-config. php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down. * * Are you sure you have the correct username and password? * Are you sure that you have typed the correct hostname? * Are you sure that the database server is running? * Here is what I know: * My hostname is correct: localhost My username and password are correct * Here is one possibility: * After I downloaded Wrodpress onto my desktop I change the name of the folder. I then uploaded that folder (w/ the new wp-config info) onto my server. * Stuck. * Any help would be appreciated… Viewing 13 replies - 1 through 13 (of 13 total) * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [17 years ago](https://wordpress.org/support/topic/error-establishing-database-connection-17/#post-1053197) * Most times, there is something wrong specified in your wp-config.php file.
