Oops! Something went wrong... A preliminary status check for the search environment has failed. The most common reasons for this are that the target Ektron site is currently being crawled, Solr or ManifoldCF are not running, or the search server does not meet the minimum requirements for hosting Solr. (Code: REQUEST_VALIDATION_FAILED) Logs are available for this console and for the Ektron Solr Administrative Service, which may contain additional details.
