The error log is one of the most important diagnostic tools you have. When your site encounters unexpected behaviour, PHP or Apache will write details to log files. Servebolt create a dedicated /logs/ directory with sub‑directories for HTTP and PHP logs . These files record HTTP requests, Apache errors, PHP errors and PHP slow logs . Reviewing them is critical, because even warnings that don’t crash your site hint at deeper problems.
Servebolt Optimizer (v3.5.58) brings grouped errors, PHP/HTTP tabs, level counters, and one-click copy to the Error Log in your WordPress dashboard.
Accessing the Error Log in WordPress
