Site URL has changed after the update

Sometimes after an update or any other changes you may find that your site url has changed, often with a random looking string appearing after the old URL for your homepage such as: http://examplesite.com/?v=e786534546587qw .
To reset this problem you need to do the following: Locate your wp-config.php file and edit it to contain the following:

define('WP_HOME','http://examplesite.com');
define('WP_SITEURL','http://examplesite.com');

Obviously you will replace “htto://examplesite.com” in the above with your own website URL that you want corrected. You can find more information about changing your sites URL at WordPress Codex.

Update PHP VersionUpgrade your PhP: Most hosts will be running the latest version of PHP but if you self host or your host is not using the latest version then this can cause compatibility issues. You can check the version of your PHP by using the Health Check plugin. If you do need to update your PHP each host has slightly different methods for updating but you can read more about it at WordPress Codex. You may also read here about PHP version and why it matters for your WordPress website.

Disable WordPress PluginsDisable all of your plugins: Sometimes problems are caused by a conflict with a plugin after an update. So disable ALL of your plugins and see if the problem goes away. If the problem goes away then you know that the problem is a plugin conflict. You then need to enable each plugin one at a time until you discover which plugin is causing the issue. You can then either leave it disabled or find an alternative version as there are many different plugins out there with similar functions. If you cannot disable your plugins directly from the dashboard then the following instructions will show you how to disable them. You may also read here about possible plugin conflict issues.

Twenty Fifteen WordPress ThemeUse the Twenty Fifteen theme: occasionally the problems are caused by conflicts with the theme that you are using. So switch to the default Twenty Fifteen theme to see if your problem goes away. If it does then you know that your solution is to get your theme updated or to switch to another theme that is compatible with WordPress 4.3.1. If you cannot access the dashboard to change your theme then you can remove all of the other theme folders via FTP so that the site is forced to use Twenty Fifteen as it is the only theme available.
