    We’ve started getting hundreds of the following PHP Fatal errors into the logs:

    ob_start(): Cannot use output buffering in output buffering display handlers in /public/wp-content/plugins/cookiebot/src/lib/buffer/Buffer_Output_Tag.php on line 101

    Is there anything we can do to patch this?

    Hi, 

    Thank you for your patience and for reaching out to Cookiebot support. 

    Please check if the Cookiebot WordPress plugin is up to date on your site.

    If you’ve already updated the plugin and are still encountering the problem, we’ll need some additional information to assist you further:

    1. Debug Information: Please provide details, including the PHP version you are using, the WordPress version, and a list of any other active plugins on your site.
    2. Background on the Error: When did you first notice this error? Information on what might have changed around that time (e.g., updates to other plugins, changes to the theme, server updates) could help diagnose the problem.

    2. From the error logs I can see that it started happening on 1st of August, and it most likely the day I’ve updated the Cookiebot plugin to the latest version

    Please update to the latest version of Cookiebot that we released today, and check if that resolves the issue. If the problem persists, I will escalate the case to our developers for further investigation and resolution.

    I can still see the error in the recent logs after updating the Cookiebot plugin to the latest version.

    Thank you for the update. Please mention the domain in question and the Cookiebot user account (email), so I can create a case for the developers to investigate.

    Could you please provide an update on any recent developments regarding the issue causing broken pages? Those are getting cached in our case and to prevent this, we’re forced to deactivate the plugin.

    I’m having same problem, all is up to date.

    Try reinstalling the plugin, it helped in my case.

    Try this, still getting this error
