**Setup:**
MW 1.25.2, PHP 5.4.45, TitleBlacklist REL1_25
**Issue:**
I get the following notices
```
PHP Notice: Use of undefined constant TBLSRC_LOCALPAGE - assumed 'TBLSRC_LOCALPAGE' in /.../w/LocalSettings.php on line 512
PHP Notice: Use of undefined constant TBLSRC_URL - assumed 'TBLSRC_URL' in /.../w/LocalSettings.php on line 516
```
when LocalSettings.php contains "wfLoadExtension":
```
## TitleBlacklist
wfLoadExtension( 'TitleBlacklist' );
$wgTitleBlacklistSources = array(
array(
'type' => TBLSRC_LOCALPAGE,
'src' => 'MediaWiki:Titleblacklist',
),
array(
'type' => TBLSRC_URL,
'src' => 'https://meta.wikimedia.org/w/index.php?title=Title_blacklist&action=raw',
),
);
```
while line 512 and 516 are the ones with 'src'.
No warnings when LocalSettings.php directly invokes:
```
## TitleBlacklist
require_once "$IP/extensions/TitleBlacklist/TitleBlacklist.php";
$wgTitleBlacklistSources = array(
array(
'type' => TBLSRC_LOCALPAGE,
'src' => 'MediaWiki:Titleblacklist',
),
array(
'type' => TBLSRC_URL,
'src' => 'https://meta.wikimedia.org/w/index.php?title=Title_blacklist&action=raw',
),
);
```
