How To Fix Mediawiki Internal Debug Error

Here are a few simple steps that should help resolve the mediawiki internal error issue.

One of the first things you’ll learn is that “echo” shouldn’t work at all; This is part of the overall design.

PHP Error

To access PHP errors, add this to the second line from top to bottom (to the right of each ) of the LocalSettings.php file:

This will definitely result in PHP errors appearing on the page. This can make it easier for attackers to find a way to negotiate with the server, but disable it if you find a specific problem.

Please note that PHP fatal errors may occur before your lines above are executed, and they may not occur all the time. Fatal PHP errors were usually logged when Apache returned to the error log - be sure to check the error_log setting in php.ini (or use phpinfo()). ).

There are several configuration options to support debugging. All subsequent ones will be false by default. Enable them by setting these animals to true in LocalSettings:

  • $wgShowExceptionDetails php Allow display of additional content (for example, tracingand stack) on the fatal error page
  • $wgDebugToolbar A video toolbar on the site combined with profiling, log messages, and/or other features.
  • $wgShowDebug Adds half of the wgDebugToolbar "Log Messages" to a regular page as a power list.
  • $wgDevelopmentWarnings MediaWiki will raise warnings about some potential bug-related health issues and deprecated features.
  • Enable Display_startup_errors

    Some vendors disable display_startup_errors, which masks errors a lot if you increase certain levels of error reporting. No more ignition with the program! Instead, you should create a wrapper file for your closure file. In the case of MediaWiki, due to mediawiki/index.Errors, you can just say it above

    In php:

    Sql Logs All SQL, Instead Looking At The Specific One That Threw The Exception, $wgDebugDumpSql Is Placed In LocalSettings.php:

    Advanced Debugging


    debug mediawiki internal error

    For many common configurations (also PhpStorm when using MediaWiki-Vagrant) see How to get back to debugging/with MediaWiki-Vagrant and PHPStorm.


    If you are using the PHP Zend interpreter, you can debug your interpreter with XDebug. MediaWiki-Vagrant supports built-in settings for this type. If you don't have MediaWiki-Vagrant, but your configuration is considered similar, you can reuse some of these values. In many cases (for example, due to a very strong firewall), you may need to use the IDE on a real machine as a web server. In this case, your requirements can be easily determined:

    To debug a real command line script (e.g. PHPUnit, maybe a maintenance script) in MediaWiki-Vagrant use:

    Tweak the script, settings, etc. on the host (this should be the IP of the person where your IP is, should actually work for MediaWiki-Vagrant) as needed.

    For more information, log profiles and errors are publicly available.

    Setting up debugging almost any log file

    To log errors with debug information in the report, add $wgDebugLogFile to this LocalSettings.php file. Change the get text to the file where you want to store all debug trace output.

    The program must have permissions from your operating system to create and write to this file, e.g. www-data.Here is the select option:

    This file contains detailed debugging information for MediaWiki Basic and Extensions.Subsystems.Some write to custom logs, see #Create a custom log file to view their output.

    Database lifecycle pin debugging can be enabled for databases with $wgDebugDBTransactions.

    Warning: The debug log file can contain personal hints such as credentials, cookies, and form-submitted data values. If this information were available, attackerscould make it public in order to hack and manipulate your computer and user script. If you absolutely have to share the debug log for analysis, go to the no-login wiki and remove all COOKIE lines from the debug log and don't get any login attempts.

    Create a store file

    MediaWiki protocol version:


    Prior to MediaWiki 1.32, the wfErrorLog() function could be used to create a custom log file that would actually only contain your defined debug words.This effort requires arguments, two compound strings for the log, and a specific document file path:

    Create custom log groups

    If you're actually debugging several different components, it can definitely be very useful to tell log groups to write data to a separate file.See $wgdebugloggroups for more information.

    To set up custom groups, enter LocalSettings.php with the following basicsExplicit functions:

    To be a member of one of these groups, create a wfDebugLog as follows:

    Writing ezine files to the /tmp directory may not trigger the journal at all, even assuming /tmp is writable by anyone. This can happen if your technique is one of the systemd functions that creates a real /tmp virtual directory to work with. If so, set up the log file to write to a new directory, such as /var/log/mediawiki


    Structured logging

    MediaWiki version:


    Structured logging allows them to include your fields in reports.For more information, see Structured logging.
