Cannot add more skills or stages in Portfolio without an error on timeline

[Melissa Wilson]

If I try to add another skill set to a stage that is already configured, when I recalculate it comes up with an error and the timeline for project completion cannot be seen at the end.

If I add another stage it throws up the same error - how can I resolve this?

Hello Melissa,

That error message sounds like the behaviour described on this bug. Could you take a look at it and match the version with your plugins version?

Cheers!
