{Task \"^1\" in \"^2\" cannot be completed in the time allocated because there is a scheduling conflict between this task and another one to which it is linked.}Try the following:

\- Change the type of constraint on the successor tasks to As Soon As Possible or some other constraint that doesn't fix it to a specific date.

\- Remove the link between the conflicting tasks.

\- Shorten the duration of one of the tasks.

\- Change the start and finish dates of one of the tasks.

\- If the task to which \"^1\" is linked is not constrained and it is a summary task, check the constraints on the subtasks.
