Because we changed the domain names for the etcl word-press site, we had to make changes to the wp-options table (WordPress address and Site address) and a global search and replace in the posts table because the URL field for each post has a hard-coded absolute URL which had to be changed. Based on instructions at http://codex.wordpress.org/Moving_WordPress. It is important to make the changes in all the paths while there is no activity in the WordPress GUI.
