Details
Set this to current time to invalidate all prior cached pages. Affects both client- and server-side caching, including assets controlled by the ResourceLoader.
For a quick copy-paste you can use the following line, whose timestamp is generated via {{CURRENTTIMESTAMP}}:
$wgCacheEpoch = 20230412125921;
If you are using a Unix-like system you can get the current date by entering the following on the command-line:
date +%Y%m%d%H%M%S
To force a file, such as "LocalSettings.php" to be re-read when touched, you can use the following code (MW < 1.17):
# When you make changes to this configuration file, this will make sure that cached pages are cleared.
$wgCacheEpoch = max( $wgCacheEpoch, gmdate( 'YmdHis', @filemtime( __FILE__ ) ) );
Since version 1.17 of MediaWiki, you should use $wgInvalidateCacheOnLocalSettingsChange to automatically invalidate cache whenever "LocalSettings.php" is modified.
