Oftentimes, logs provide essential information about a given issue, such as the MediaWiki Internal Error.
Check Server Requirements
MediaWiki, similar to other CMS platforms requires specific software versions and extensions, so it functions properly.
Make sure that:
- Your PHP version meets the requirements of the MediaWiki version. To check your PHP version, log in to the AwardSpace hosting panel and head to Hosting Tools -> PHP Settings:
After that, use the drop-down menu within the Change PHP Version section, so you align the PHP version with the MediaWiki version you are currently using:
- Verify that the database version is the one required by your version of MediaWiki. To check and potentially change the database version, via the hosting panel, go to Hosting Tools -> MySQL Databases:
Within this page, go to the Database Version drop-down menu and select the version that suits the version of your MediaWiki installation:
Check Localsettings.php Configuration
Sometimes, the issue can be rooted in the core configuration files of MediaWiki. Such is the LocalSettings.php file. You should open this file and verify such settings:
Database Settings:
$wgDBtype = “mysql”;
$wgDBserver = “localhost”;
$wgDBname = “database_name”;
$wgDBuser = “database_user”;
$wgDBpassword = “password”;
Paths:
$wgScriptPath = “/path_to_mediawiki”;
$wgServer = “http://yourdomain.com”;
To find the LocalSettings.php file, log in to your AwardSpace hosting panel, and head to File Manager->Your MediaWiki root folder->LocalSettings.php:
Disable Problematic Extensions and Skins
Sometimes, poorly crafted MediaWiki extensions and skins can cause errors. Should this be the case, you should locate the faulty extension/skin and contact developers, or replace it with a functional one.
The process goes as follows:
- Open your Extensions or Skins directory.
- Disable the first extension/skin in the list.
- Open your MediaWiki website.
- If the Internal Error Message is still present, go to the extensions/skins directory, activate the disabled skin/extension and deactivate the next in the list.
- Repeat this process until you deactivate a skin/extension that doesn’t prompt the Internal Error message.
- Once you locate the problematic skin/extension, contact developers for further support or completely remove it from your system.
If none of your skins and extensions causes the MediaWiki Internal Error message, then the problem lies elsewhere.
Reinstall MEdiaWIki Core
If everything else fails, consider reinstalling the platform. To do so, download the latest MediaWiki version of the official website and replace the newly downloaded files within the AwardSpace root directory.
