Task list problem. Completed tasks became unfulfilled.

[Deniz]

Hey!
The page hosts tasks on users using a task list macro. Users completed their tasks by ticking the checkboxes. There was a problem, completed tasks for some reason again became unfulfilled, i.e. the checkmarks were removed from the tasks.
Why did the marks on the completion of tasks on the page fly off?
How to see who took them off or why they flew off (The tasks were definitely completed).

Hi @Deniz ,

Just to clarify.. You have one single page with multiple task lists for different users? If so them I am thinking that those task lists do not have unique IDs and when someone check/uncheck it it check/uncheck in a different task list on the same page.

In general please check this KB article if this affects you
