Found a solution – for me at least:I changed the database number in
wp-includes\ version.php

My hosting is with Webfusion and I upgraded to WordPress 3.8 when things went tits up.

First I attempted to follow the instructions in this very handy link.

Essentially access your databse via whatever method your hosting providor offers.
Intructions on how to do this will probably be in a email from your hosting providor …somehwhere.

If you’re stuck for a user name and password have a look inside your wordpress install via FTP. There’s a file there called wp-config.php

The Db username and Db password can be found in there

However when I tracked down suitable entry in phpMYadmin for updating the value of the databse version I din’t have permissions to edit it. Not sure why.
But I did get the value and write it down… in this case the database version was “25824”

Then,
via FTP I went into the WP-Includes folder
found Verision.php

and edited the file so the values in version.php and the db_version entry in the database matched. So it looks like this

$wp_db_version = 25824

<?php
/**
 * The WordPress version string
 *
 * @global string $wp_version
 */
$wp_version = '3.8';

/**
 * Holds the WordPress DB revision, increments when changes are made to the WordPress DB schema.
 *
 * @global int $wp_db_version
 */
$wp_db_version = 25824

/**

Then, hey presto, I was able to access my wordpress dashboard.

Hopefully this nonsense helps someone!
