WordPress Website has made life easier for the user and the developers, as it already consists of an inbuilt debugging mechanism, which will tell you the line, in which the error lies, along with telling you the kind of error it is, by showing the error message

Debugging shows you the errors and what you are doing wrongly. It does not necessarily tell you the solutions to the errors. To do so, you need an expert Website Developers or a quality Website Development Company to do the job.

Enabling Debug Mode in WordPress

WordPress has an inbuilt debugging method, that needs to be enabled. Couple of ways for enabling the WordPress Debug Method:

The process of enabling a Debug Mode manually is short, if you know what to do. You need to access the wp-config.php file and insert some constants. The wp-config.php file is initially available in the root folder (if you have not changed the location) of the server (which you are using) file. 

The script that needs to be written in the wp-config.php file is 

Define (‘WP_DEBUG’, true);

In the scenario, where you want to disable the WordPress Debug Method, you can add the following script, in the wp-config.php file

Define (‘WP_DEBUG’, false);

In the occurrence of any type of confusion, it is advised to take guidance from a reputed Website Development Company

WordPress Debug Log:

Multiple Errors can be existing in the code of your WordPress Website. If you have the debug mode enabled, you will get the error message while debugging, but it will not be saved. This can be an issue, as it is not a guarantee that you will remember all the errors that you have had encountered. 

It is suggested to enable the debug log, as it allows you to create and maintain a file, recording all the errors that you have encountered. The Debug Log can easily be enabled via setting of the WordPress Panel. The list of errors is managed in the “debug.log” file, which is available in “wp-content” folder, found inside the file of the server, which you are using. 

The “wp_debug_display” is only operated, if and when you do not want to display the error message while writing the code, but want to have it stored in “wp-content” folder.

Was this too much information for you take in? Not to worry, as you can make your choice of a Website Development Company among so many good one’s available.

When to Enable Debug Mode

Just because you have something available, it should be used at all times, regardless of whether you need it or not. The Debug Mode should only be enabled, when you are troubleshooting errors with WordPress. If you have it enabled all the times, the user might get the error message of the code, while they are visiting the website.

The way to Disable the Debug Mode is pretty much the opposite of enabling the Debug Mode, as it is also mention above. You can either add the following script in the wp.config.php file

define (‘WP_DEBUG’, false);

Other way to Disable Debug Mode is to clear out the script, that you used for enabling the Debug Mode in the first place.
