Save and revert button aren't available in Sync Gateway admin

I just installed an instance of Couchbase Server 5.1.1 and Couchbase Sync Gateway 1.5.2 on my local machine (Windows) and I face a strange issue, the ‘save’ and ‘revert’ button of the SG admin aren’t available.

We can see here on an instance of Couchbase Sync Gateway 1.5.1 on a Ubuntu machine that the buttons are visible:

But here is what I get on my local machine:

FWIW, the Sync Gateway admin UI is not an officially supported product. To that end, it’s not actively maintained or developed. So I would not be surprised if you see glitches.

Please use the Sync Gateway REST API instead.

An official version of the admin UI is under consideration .

Also, while it won’t fix the issue, in general, you may want to use the latest version of Couchbase Server (5.5), Sync Gateway (2.1)…unless you have a reason you cannot upgrade.
