Title: Error establishing a database connection Last modified: August 19, 2016 --- # Error establishing a database connection * [David McGavin](https://wordpress.org/support/users/david-mcgavin/) * (@david-mcgavin) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/) * WordPress has been up and running for months (v2.9.1 prefix ‘spn_’)on [http://www.spanishpropertynews.com/](http://www.spanishpropertynews.com/). * Last night I ran another WordPress installation (v3.0.4) for a different domain using the same database (prefix ‘wp_demo_’) since then the above domain no longer works. Error Message: **Error establishing a database connection** * I have checked the usual (several times) i.e. db_name, db_user, db_host, db_password and all is as it should be. The second domain is using the same database config data and it work fine. * Please help…. after several hours of checking and re-checking, changing and saving values – still no joy! * Thanks in advance David Viewing 7 replies - 1 through 7 (of 7 total) * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/#post-1894516) * did you make the change in wp-config.php of each install to corresponding prefix * [kirota](https://wordpress.org/support/users/kirota/) * (@kirota) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/#post-1894533) * Hi! * I have the same problem.. I am trying to install it for the first time, so maybe I did some kind of mistake? This is the message I get, but it also could be that there is something with server because I couldn’t reach File manager for almost 24 hours.. Maybe I should wate a bit more?

It could be that I don’t see the mistake( which can happen when you try to find it) or it is just the server problem.. Do I have to do anything else but to change these settings? * [mackehansson](https://wordpress.org/support/users/mackehansson/) * (@mackehansson) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/#post-1894546) * I get the same message after upgrading to 3.0.4? * Is this problem related to the new release? * [kirota](https://wordpress.org/support/users/kirota/) * (@kirota) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/#post-1894554) * Could this be my problem? * > MySQL external access – Available on premium only – Upgrade * Thread Starter [David McGavin](https://wordpress.org/support/users/david-mcgavin/) * (@david-mcgavin) * [15 years, 3 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-264/#post-1894688) * Hi all, Thanks for your input. * I have re-checked the config file and the data for database name, user, password, host and table prefix are correct (as per MySQL Admin /CPanel). * There is nothing wrong with the database server because I’m using another installation( v3.0.4) is working fine. This installation is sharing the same database (i.e. name, user, password and host) the only difference is the table prefix. * I have tried everything (I think?) including changing the prefix to null (”) saving the config file and then re-editing it and changing the prefix value back to ‘spn_’. But still no joy! * I’ve even gone as far as to rename the database table prefixes and then re-edit the config file. Guess what?, still no joy!! * Any other ideas? * Thanks in advance for your contributions. David.
