Ok 2 things here. First via this i've found out that the BlackList feature in 1.5 version was not working properly. This has now been fixed (for 1.5.3).
Second, i 'think' i can see what's going on, but have no clue why. Basically in the MC version there is no </graph> in the xml that is sent to the FusionChart code. I'm pretty sure this is what is causing the problem, but as that comes out of Tienda, i don't know how to fix. See image below.
For now, you should blacklist Tienda until we can sort out what's going on there (when 1.5.3 is released of course).
well, i was unable to find out what the problem was. It looked like something different coming out of Tienda in the URL for the chart. I'm not doing anything to that so not sure what is going on. Blacklist works again now in 1.5.3 so my suggestion is to blacklist it.
i have opened a bug report with tienda and they are having the template guy working on it, but they say that they doubt its something wrong with them since tienda works fine on all of the other admin templates they have used..
yah not sure with this one, i tried turning of the phpQuery stuff in MC which really is the only thing that could affect the output, and it made no difference.
