    Dear support,
    after the last update, if I connect to a specific page (only one), the site state this error:

    Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

    If I deactivate the plugin, the page is loaded correctly (If I reactivate it, the problem occurs again).
    How to resolve?
    Thanks

    Hi,

    I will be happy to assist you with the issue you are facing.

    It seems like a conflict with one of the plugins or the theme you are using. To determine that, can you please follow this troubleshooting guide?
    https://rankmath.com/kb/check-plugin-conflicts/

    Only the site admin would know and your users won’t be affected by this troubleshooting.

    If that doesn’t work, we might need to take a closer look at the settings. Please include your WP logins in the designated Sensitive Data section.
    Sensitive Data Section

    It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
    https://wordpress.org/plugins/temporary-login-without-password/

    You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):
    https://wordpress.org/plugins/wp-security-audit-log/

    We really look forward to helping you.

    Dear Todd,
    thank you for your answer. Just before applying the procedure suggested via site Health Check plugin, the problem got solved with a wp database optimisation.
    Thank you.

    Hi Todd,
    the issue occurred again. I checked with the “Confirming a Theme/Plugin Conflict With Rank Math” method and I noticed that the problem is almost surely the theme, Pro Theme by Themco, its child theme in particular.
    How to proceed in order to resolve the issue?
    Thanks

    Hi,

    We are sorry to hear you are facing an issue with your theme.

    Please contact your theme provider and see what they say.

    They should be able to give you an answer.

    Sorry Todd, my bad, I rechecked: it seems that WPML plugin (https://wpml.org/it/) is the real cause of the issue.
