Survey theme/template: Vanilla extended
==================
Hi there
We successfully redeveloped/upgraded a vanilla extended 5.6 theme into a working 6.x theme back in April last year in our test environment, but logging in to the environment this week I can see that LimeSurvey no longer regards it as compatible in the most recent release (error message: "The theme is not compatible with your version of LimeSurvey").
Does anyone have any idea of the changes that might have occurred to make a previously compatible 6.x theme become in the recent 6.x releases?
I can see this open bug, for instance:
bugs.limesurvey.org/view.php?id=19006
I'm hoping that there might be a simple fix, eg, there are missing flags in config.xml file or similar.
Thanks for your help.
