Thread:Extension talk:Wikibase Repository/Wikibase extension error - failed to deserialize on EntityFactor.php

I installed the extension wikibase following the steps defined on the page: https://www.mediawiki.org/wiki/Wikibase/Installation This is the configuration I have in LocalSettings.php file: require_once( "$IP/extensions/Wikidata/Wikidata.php" ); $wgEnableWikibaseRepo = false; $wgEnableWikibaseClient = true; $wmgUseWikibaseRepo = false; $wmgUseWikibaseClient = true;

require_once "$IP/extensions/Wikibase/client/WikibaseClient.php"; require_once "$IP/extensions/Wikibase/client/ExampleSettings.php";

$wgWBRepoSettings['entityNamespaces'][CONTENT_MODEL_WIKIBASE_ITEM] = NS_MAIN; $wgWBClientSettings["siteGlobalID"] = "enwiki";

Attached the following error trace im getting when I try to render a page:

[87a3f0c9] /en/index.php/Ian_Paisley Exception from line 163 of /data/servers/wikimirror_mediawiki_renderer_apache/htdocs/gitExtensions/extensions/Wikidata/extensions/Wikibase/lib/includes/EntityFactory.php: failed to deserialize
