Error After Changing URLs in WordPress General Settings


March 6, 2014

Recently, a client decided to purchase an alternative domain name for their existing website. They decided to log into their WordPress dashboard and start poking around. They changed the WordPress Address and Site Address under General Settings to the new domain name. Needless to say, this wasn’t a good idea. After the changes were saved, the website was no longer functioning.


The site wasn’t displaying and I couldn’t access the WordPress login to get to the dashboard. In order to correct the issue, I needed FTP access so I could modify the wp-config.php and functions.php file.

The following code can be used to manually define a website URL through the wp-config.php file.


Within seconds the website was working.

However, I was faced with another issue. When I logged in to WordPress and went back to the General Settings, the text fields were disabled.


In order to edit these fields, I added the following code to the top of the functions.php file, immediately after the initial “<?php” line.


After I uploaded the new version of the functions.php file, I removed the code that was added to the wp-config.php file.

When I logged back into WordPress, the text fields under General Settings were editable.

The last step was to remove the code that I added to the functions.php file and the issue was solved.

    This is actually accurate except for one point, you should have mentioned that the functions.php file to be edited is not the one in wp-include but the one found in our current themes folder.

    We are facing a wired issue , we are replacing the site url and home url in wp-config.php and database both .

    Webiste is redirecting to new url but showing message “page ok” .Also wp-admin is not opening after these changes .

    We refer all the below steps :

    checklist for wordpress migration is:

    edit database table wp-options and options siteurl and home there
    edit wp-config.php (DB_NAME, DB_USER, DB_PASSWORD a DB_HOST)
    use this replace script to replace all other occurences of absolute paths for relative path, it is enough to replace your old site name with an “/”
    also you want to regenerate static links, in Settings menu go to permalinks and just click on save.

    what to do in that case ??
