Hide Content
if you installed the theme sample content, the default Portfolio page includes a Topic List block that displays the "Projects" topic tree.
Do you remember deleting the Projects topic tree (Dashboard->System&Settings->Attributes->Topics).
If so, I think that is the cause for the error.
Anyway, this is a bug. The page should not show an error even if the tree no longer exists.
I have released a new version of the theme fixing this. Could you update to the latest version and see if the issue is solved?
(You should be able to update the theme by going to Dashboard > Extend Concrete 5 > Update Add-ons)
Please let me know if this fixes the problem,
Jordi
