Sorry, for the delay in response. Our issue has been resolved 2 weeks ago when reading Merging Tickets fails in 3.5 and followed up on that.
We still have the (small) issue of the difference between the numbering in the #ticketnumber and the URL number wich are different. The URL-number is 1 higher than the ticketnumber in the text. Is there a way to fix this? Thanks in advance.
