To reproduce in KTD: - Start KTD with Elasticsearch, e.g. $ ktd --search-engine es7 up - Stop Zebra: $ sudo koha-zebra --stop kohadev - Go to About Koha For "Zebra status" there is a warning in bold letters on a red background: "Zebra server seems not to be available. Is it started?" I would say it is OK to have a warning there about Zebra not running, but if SearchEngine = Elasticsearch it should not look like there is a serious problem with the system. Non-bold letters on neutral background should be enough.
