bootstrap sub theme rendering garland I copied the database and source code from my local to another server. 
On my local I have a bootstrap sub theme set as default which works fine. On the other server (which has the exact same db settings and code) the theme being rendered is Garland despite being disabled and the admin section under appearance stating that my sub-theme is the active one.

When I checked the site after updating the server it had the correct css but when I reloaded the page it reverted back to garland but without any changes to the admin settings. 

What are some good steps to take in terms of debugging this.
I deleted the garland theme and re-added it. After this everything worked properly. I don't know why this worked!
