Error with PHP 5.3+
The following error occurs with SmoothGallery extension and PHP 5.3:
Detected bug in an extension! Hook smoothGalleryParserOutput failed to return a value
This is solved by changing the line in SmoothGallery.php:
function smoothGalleryParserOutput( &$outputPage, &$parserOutput ) {
to:
function smoothGalleryParserOutput( &$outputPage, $parserOutput ) {
Mediawiki specifies that the second parameter is not a reference, and when it was one, it broke the hook completely.
