These instructions is for our clients using the Advanced Managed VPS Hosting for WordPress service powered by Convesio.
SKILL LEVEL - You will need to know how to use an SFTP App/program and understand your WordPress site's file structure on the server.
From time to time you might have issues with your WordPress powered website, and activating the Debug mode in your WordPress will help to see if your WordPress is throwing any errors.
Here are the steps to do so:
[1] You will need to obtain your SFTP details for your site. These are easy to find, in your KartHost Customer Center account, click on the SERVICES block, then on the 'My Products & Services' page select your WordPress hosting account and click the "Active" button to the right under 'Status'. Then on the resulting 'Manage Product' page scroll down until you see the 'Additional Information tab'. Then you will see information regarding your specific Platform. Including SFTP Details. (Note: you must use an FTP App that can connect using SFTP, all modern FTP Apps can use SFTP. We recommend Filezilla if you do not have one, its free and widely used)
[2] Now after connecting to your Platform using SFTP in the WordPress web root directory (var/www/html/wordpress), look for the wp-config.php file (HIGHLY RECOMMEND YOU DOWNLOAD this file as a BACKUP). And then open the file with a tool like PSPad, Notepad++, Notepad (comes with Windows computers) on a Mac try 'TextEdit' (but make sure it's in plain text mode), or any other HTML/PHP editing app you would prefer to use.
Open the wp-config.php file and add this code:
define('WP_DEBUG', true);
Place the above code below this code
/** The Database Collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );
[3] When done, it should look like this
/** The Database Collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );
define('WP_DEBUG', true);
[4] Keep in mind that when adding the DEBUG code to the wp-config.php file, due to security reasons, once you have finished with your research, make sure to either remove the full code you added OR, just change 'true' to 'false'. It would look like this:
define('WP_DEBUG', false);
[5] Any errors that are generated by your site will appear in the header area on your site and in the Admin area. - Save the Error codes you see and then follow the advice in step 4 above.
