How To Turn On Debug Messages For WordPress

This simple thing will help you find the best solution for getting rid of the most WordPress errors. I already mentioned above the “WordPress debug” feature. Below I will make a special section about it.

By default, WordPress will turn off all debugging messages so the visitor to the site can’t see any error messages showing anything wrong with the code.

If you do any WordPress development, such as new plugins or theme development, this can cause a problem as you won’t see if you have any settings wrongs.

Turning on debug mode will display all warnings or error messages you have with any installed plugins or themes. The “WordPress debug” feature makes it easy to spot outdated or use old WordPress functions that are not supported anymore.

Turn On Debugging

To turn on debug messages you need to open up your wp-config.php file and find the line.

define('WP_DEBUG', false);

Comment out this line a replace it with.

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

Please Note

You must remember to turn this off when you put your website live or the visitor will be able to see all your debugging messages.

Looking for a Wordpress transfer from site A to site B, I found back Andrei from Wesites Seller on Google.He was very proactive in his approach, came with hundreds of ideas and lifetime experiences from other migrations. He knows the wordpress, the hosting and php database as the back of his pocket.And we worked out this migration very smooth. Together we solved it, and myself and my business are very pleased with his approach.100% recommendation & kudo's from out of Belgium!

Websites Seller built my resume site. Deliverables were quickly completed, and I was asked for my feedback at each stage of development. All feedback I gave was implemented in a short time.Another great thing is that he comes with smart solutions, regarding stuff which I didn't initially think of (site security, Google site speed optimization and so on). Basically, he was great, staying in touch, keeping me updated and paid attention to what was most important for my site.Overall, I am very happy with the work done. I highly recommend this developer!
