title: "Explore" button disappeared from the SQL Lab tab of the Apache Superset
body: <p>Not sure what caused this, but now I do not have &quot;Explore&quot; button in the SQL Lab, which I used to create virtual datasets, only &quot;download to CSV&quot; and &quot;copy to clipboard&quot;. I have latest version of the superset launched using docker-compose, no errors or warnings in the log, and I use postgres database to store data. Week ago this button was in place, perhaps the only significant change since those times - I deleted all example charts/datasets and database, which superset created on the first start.</p>
  <p>Any ideas what I could check are very appreciated.</p>
