im_presto Posted January 8, 2016 Share Posted January 8, 2016 I have just tried 1-click upgrade from 1.6.1.0 to 1.6.1.4. it was seemless and no issue raised. Turn debug mode on in your configuration and then see, there may be errors related to missing code or db related. Link to comment Share on other sites More sharing options...

im_presto Posted January 12, 2016 Share Posted January 12, 2016 Issues may arise if you have override any of the classes and controller file as per your application requirement then it would raise the error. Do one thing, remove all you override files and clear cache then check. Link to comment Share on other sites More sharing options...
