Certain errors must be corrected as quickly as possible – from minor problems, to the dreaded WordPress white screen of death or a WordPress database error. WordPress Debug prevents you from having to check each individual plugin for these types of errors. Not only would that take a long time, but it is often unsuccessful. WordPress debug mode is a valuable tool that can help you to perform this task more effectively. Once activated, the error messages are displayed on the concerned pages, and you can then resolve the problem directly at the source.
At the same time, you can also determine which pages are running optimally and therefore do not require any corrections. WordPress debug is an important analytical tool as it shows you where the problems are as well as which parts of your website have been optimally designed and set up. All PHP errors and warnings are displayed at the top of the page, even if they do not (yet) have a lasting influence on the performance of your website.
Once the problem has been dealt with, simply deactivate the WordPress debug again. This is important as otherwise the text from your PHP code may be exposed to your visitors and thus pose a potential security risk. WordPress debug mode may also have a detrimental effect on the performance of your website.
