Upgrading Version 4.0.1 to 4.0.2 via upgrade section

hi,



I was trying to upgrade my system from version 4.0.2 to 4.0.3. All the installation worked good and the system said installation was successful.



When I tried to view the front end I got a error


[quote]Fatal error: Uncaught exception 'Exception' with message 'expected color value: failed at background-color: lighten(@base, 45%); line: 2' [/quote]



In theme editor I noted that the preset was kept at “–” value (no preset present)



and the default location of the theme changed to /basic then my custom directory (I cloned the theme and done all my changes with my new theme location)



Any one done the upgrade? dose it works good for you? guide me guys I just want to launch my client site.



I waited for long back for version 4.0.3 bcz version 4.0.2 was buggy.



thanks
