    Something is odd.

    If you examine the the source for email-users.php it doesn’t even have 4295 lines in it so the error above (and repeated a number of times) is suspicious.

    Standard debugging questions:

    1. What is different between your development site and the production site?
    2. Have you disabled all plugins except Email Users to see if the problem persists?

    This has the appearance of a plugin or theme conflict so narrowing down what the conflict is the first step to resolving the problem.
