This is a common problem with WordPress and you don’t need to be afraid of data loss. If you will browse your wordpress database, you will find that all your posts, pages, plug-in, themes are available at their places and nothing go deleted. This is a problem related with a table named as “WP_Options” of WordPress database. The wp_options table contains some general information related to the blog which appears in the setting tab of admin. It also contains some information about the plug-in installed for the blog.

There are mainly two reasons for this issue in your WordPress blog.

  1. The Option Name db_version in WP_Options table is not equal to the field wp_db_version of version.php. You can have a look at the Version.php located under wp-include folder of your wordpress blog.
  2. The Option Name “siteurl” in WP_Options table is not populated properly.

Follow the below mentioned steps to resolve the issue-:

  • Open the phpMyadmin from your blog’s host to have a look into the WordPress database
  • Browse the table WP_Options to see the Option_Value for the Option_Name db_version. For WordPress version 2.7.1, the db_version should be equal to 9872. Other db_versions are as below,
  • WordPress Version db_version
    2.9 12329
    2.8.1 10850
    2.7.1 9872
    2.7 9872
    2.6.5 8204
    2.6.3 8204
    2.6.2 8204
    2.6.1 8204
    2.6 8201
    2.5.1 7796
    2.5 7558
    2.3.3 6124
    2.3.2 6124
    2.3.1 6124
    2.3 6124
  • Open the PHP file version.php which is located in wp-include folder of your wordpress blog, and check the field $wp_db_version. It should be equal to the db_version of WP_Options table.
  • Below is the screenshot of version.php file from wp-include where you can see the $wp_db_version field as 9872 which refers to the wordpress version as 2.7.1

    It should be equal to the db_version populated in WP_Options table. Here is the screenshot from the same table,

  • If the fields are having same value, then the issue is with the Option_Name “siteurl” of WP_Options table. Check the value for the same. It should have the URL of your blog’s home page. Update the Option_Value of this field, and reload the home page of your blog. Here is the screenshot of WP_Options table showing the option_name “siteurl”,


In case the problem is still there for your blog, then “check all” the  tables from the wordpress database and  select “Check Table” from the option list. Once done, then try to reload the blog’s page. Here is the screenshot for “Check Table” option,


I hope that the problem related with your wordpress blog resolved by this time or you will have to restore the WP_Options table from previous backups. Please let us know your feedback thru comments section.
