Thread:Project:Support desk/Resource Loader errors following directory change/reply (3)

$wgInvalidateCacheOnLocalSettingsChange has nothing to do with the errors described. (Unless the error message involves the stat failing for LocalSettings.php )

This particular issue was fixed in MediaWiki 1.19 (r94433 to be exact).

As for why the warning stopped, I would guess that a RL-related cache either expired or was invalidated, but I'm not really familar with how RL does caching so I can't really say much on that subject.
