Issue

Fatal error: Uncaught Error: Undefined constant "SBL_PROP_PARENTPAGE" in /../LocalSettings.php:358 Stack trace: #0 /../includes/Setup.php(222): require_once() #1 /../includes/WebStart.php(85): require_once('...') #2 /../index.php(50): require('...') #3 {main} thrown in /../LocalSettings.php on line 358

The issue from #56 seems to be back, this time as Fatal error.

Steps to reproduce

Semantic Breadcrumb Links

wfLoadExtension( 'SemanticBreadcrumbLinks' );

$GLOBALS['egSBLTryToFindClosestDescendant'] = false;
$GLOBALS['egSBLPropertySearchPatternByNamespace'] = [
DEMO => [
SBL_PROP_PARENTPAGE,
SBL_PROP_PARENTPAGE,
SBL_PROP_PARENTPAGE
]
];

Workaround

For now I manually required

require('extensions/SemanticBreadcrumbLinks/SemanticBreadcrumbLinks.php');

in LocalSettings.php
