[SOLVED] Burndown chart oscillation

unbelievable, i give access to an external user, i test the rules acces with two differents navigators. One navigator have a administrator acount and the other navigator is loged with the new user acount. When i test on same project with same options, with my administrator count burbdown is OK and with the new acount, burndown oscillation are displayed. see my screenshot in attachement. (Clock on the server is ok now)

test this morning with an other computer, same test same result. I test withe a switch betwin the two navigators and same result. Conclusion the problem is on the server and source code not on local computer (cache navigator or other specific local environements)

Hello,
thanks for your answer. No acces rules problem and no sub-project.

Hello,
after more tests i note the problem disappear after some time.

No no explanation, just an ascertainment

Thanks
Bruno.
