mediawiki upload size
To change the maximum upload size in MediaWiki, you need to adjust the following configuration settings in your LocalSettings.php file:
$wgMaxUploadSize = 1024 1024 20; // Set to desired size in bytes (e.g., 20 MB)
$wgUploadSizeWarning = 1024 1024 15; // Optional: Set a warning threshold if needed
$wgMaxImageArea = 1.25 1024 1024 * 20; // Optional: Adjust maximum image area
Replace the values accordingly based on your requirements.
