Data base name too long
When you install SharePoint Central Admin database using Configuration wizard, the SharePoint Admin Content database name has a name : SharePoint_adminContent plus very long GUID numbers.

Once you click Site Settings and you see no Site as template option is available. Most common reasons for this issues is that by enabling Publishing features or SharePoint does not allow to run custom scripts. As the result, it also disables web designer Galleries and Save site as template feature.
