I tried to install MediaWiki 1.22 on Windows and selected a few of the bundled extensions. Installation continues smoothly, but I cannot call MediaWiki afterwards. Instead, I get this warning:
Warning: require_once(<path to mediawiki>\mediawiki-1.22.0\x1bxtensions\Cite\Cite.php): failed to open stream: Invalid argument in <path to mediawiki>\mediawiki-1.22.0\LocalSettings.php on line 126
The reason for this is most likely that the path to the extension file is written with backslashes in LocalSettings.php:
require_once "$IP\extensions\Cite\Cite.php";
Unfortunately, \e is an escape sequence. So the resulting include path for php is wrong. Instead of
...mediawiki-1.22.0/e\x1bxtensions...
it says
...mediawiki-1.22.0\x1bxtensions...
Version: 1.22.0
Severity: normal
