Elasticsearch indexing failed for post- Elasticsearch error: InvalidIndexNameException[[Admin] Invalid index name [Admin], must be lowercase] - library/XenES/Search/SourceHandler/ElasticSearch.php:713 That is the report from server error log. My database name start with an uppercase letter, is that the issue? If yes, in phpmyadmin do I just choose rename the databse from operations, then edit the config.php to reflect the new database name? Also the database username starts with an uppercase letter, does that matter? Or am I way off? thanks for any help.
