Problem


After saving an event and dimension, the user gets an alert,? Error checking data versions: Collection was modified; enumeration operation may not execute." error.

Solution

This can be a case where a user is modifying event A and someone else is modifying event B which depends on A.
In that case there can be a discrepancy detected and you can get this message and your event is not modified.

There are some other scenarios where this could happen and still not be an indication of a serious problem.? In previous cases this is seen as an intermittent error which self-resolves.
