In this stage, I worked with errors such as the White Screen of Death and Plugin Conflict Errors. I researched these problems by analyzing documentation, forums, and real cases where incompatible or poorly developed plugins cause system failures.

One of the most important things I learned was how to enable debug mode in WordPress to reveal hidden PHP errors. I also understood how to manually disable plugins through the /wp-content/plugins/ directory when access to the admin panel is not possible.

This process helped me understand how different components in WordPress interact with each other and how a single faulty plugin can affect the entire system.
