Without any modification of the environment / plugins / installation we see the following behavior:
The action button Issue-xxx -> More Actions -> clone opens a dialog with the (expected) Clone- Dialog (enter summary..), but when I press the create-button no copy is created.
Instead, it produces two links at the same issue (cloned by and clones) which refer to the same (old issue).
No error message appears, it just does not work.
We tried to clone issue with different Issues, different users, in different projects (using different Workflows), but always with same result: no clone is made. But we know that it worked some days ago.
Any hints how to find out what's going wrong?
Thanks in advance
