Debug/Error Log

The Debug/Error Log section in Osclass helps administrators identify and resolve issues related to PHP execution, database queries, and system errors.

By enabling debugging and logging features, you can monitor system performance and diagnose issues efficiently.

Debug/Error Log Settings

  • PHP error log
  • PHP errors output to file
  • Database debug mode

These settings determine whether errors are displayed in real-time, logged into files, or debugged at the database level.

Enable Logs

You can enable error/debug logs in config.php (located in the root directory) by adding the following lines:

define('OSC_DEBUG', true);  
// Enable PHP debugging

define('OSC_DEBUG_LOG', true);  
// Stores PHP debug into a log file

define('OSC_DEBUG_DB', true);  
// Enable database debugging

Explanation of debug settings:

  • OSC_DEBUG: Displays PHP errors and warnings in real-time while browsing Osclass.
  • OSC_DEBUG_LOG: Saves PHP errors into a log file for later analysis.
  • OSC_DEBUG_DB: Enables database query logging, useful for tracking SQL-related issues.

Debug Log File

The debug log file is located in the oc-content folder. If the file does not exist or is empty, no errors or debug messages have been logged yet.

Common reasons why the debug log file may be empty:

  • PHP errors are not occurring or not reaching the error threshold.
  • Debugging is not properly enabled in config.php.
  • File permissions prevent Osclass from writing to the debug log file.

Managing Debug Logs

To effectively manage debug logs, consider the following:

  • Regularly check and clear logs to prevent excessive file size.
  • Disable debugging when running a live website to prevent unnecessary load.
  • Ensure log file permissions allow Osclass to write to the file (chmod 644 or chmod 666 may be required).

Summary

The Debug/Error Log section in Osclass provides essential tools for troubleshooting and diagnosing system issues. By enabling logging features in config.php, administrators can track errors, identify bugs, and improve overall system stability.
