Sugar charts not appearing after upgrade to 6.2 beta

[mindkiller]

Hi, upgrade from 6.0 to 6.2 beta went smoothly, no error messages and everything seems to be working, except none of the charts can be displayed... I can see the chart heading, edit the properties, etc. but no chart is displayed.

Previously I at least used to get message "Data not available" which is fixed with permissions but now it's simply blank...

Any ideas please?

thank you

Sorry, it was down to permissions in Include folder....
