Todas mis páginas de MediaWiki están en blanco

Question

De repente, todas mis páginas de Mediawiki están en blanco. Si hago clic en el campo de edición, el contenido sigue ahí. He comprobado el archivo sqlite y se ve bien. He activado la salida de depuración y obtengo lo siguiente:

¿Es probable que estos errores sean la causa del problema? Si es así, ¿cómo lo resuelvo? Y si no, ¿alguien tiene alguna idea sobre cuál podría ser el problema?

Answer 1

Debes cambiar includes / MagicWord.php como se muestra aquí: here

Reemplazar

$group = "(?P<{$i}_{$name}>" . preg_quote( $syn, ''/'' ) . '')'';

Con

$it = strtr( $i, ''0123456789'', ''abcdefghij'' );
$group = "(?P<{$it}_{$name}>" . preg_quote( $syn, ''/'' ) . '')'';

Después de reemplazar esto tienes que purgar todos los sitios. Esto se puede hacer en páginas individuales agregando "? Action = purge" a la URL de la página o para todos los sitios ejecutando esto en la línea de comandos desde el directorio de mantenimiento:

php purgeList.php --purge --all

Answer 2

Encontré el problema. Se describe en este informe de error . Aparentemente está arreglado en el maestro de Mediawiki. Las versiones publicadas no son compatibles con PCRE 8.34.

Answer 3

Tuve los mismos síntomas después de actualizar de Trusty a Xenial (Ubuntu), pero no fue un problema de PCRE. en mi caso, se resolvió deshabilitando la extensión Widgets, lo que hice al comentar esta línea en LocalSettings.php ...

require_once("$IP/extensions/Widgets/Widgets.php");

Tengo la v1.0 de Widgets en v1.28.0 de Mediawiki.
