    Hi @dzampyy,

    I see the line 35 in that error is trying to set a Cookie, however, that PHP Warning: Cannot modify header information - headers already error is strange as it is most often caused by issues with faulty code in a plugin file (i.e. whitespace where it shouldn’t be).

    As a first step, reinstalling a fresh copy of the plugin should help ensure there are no files that got corrupted when updating. I’d recommend taking a full backup of the site first, just in case. After that you can download a copy of the plugin here:
    https://ww.wp.xz.cn/plugins/mailpoet/

    Then we have a guide for re-installing via FTP here:
    https://kb.mailpoet.com/article/258-re-installing-updating-the-plugin-via-ftp

    If you are still seeing the same issue after reinstalling, then another good step to try would be a conflict test. Testing to see if the issue occurs with only MailPoet active, and a default theme like Twenty Twenty would help to rule out any conflicts. We have a guide for conflict testing available here:
    https://kb.mailpoet.com/article/204-how-to-test-for-plugins-conflict

    Please let me know how that goes.

    Hi there @dzampyy,

    Thank you for the clarification.

    Performing that conflict test that @bruberries recommended would still be the next best step here to try to narrow down which plugin is causing those warnings. As mentioned, those warnings generally come from faulty code in plugins, such as whitespace in plugin files where it shouldn’t be.

    Testing to see if the issue occurs with only MailPoet active, and a default theme like Twenty Twenty would help to rule out any conflicts. We have a guide for conflict testing available here:
    https://kb.mailpoet.com/article/204-how-to-test-for-plugins-conflict

    After that, you can switch your theme back, and re-activate plugins one by one to see when the issue returns. The last plugin / theme that was activated would be the culprit in that case.

    Best of luck!
