Update to V12.0 broke site

Hi @scldad

Thank you for reaching out and bringing this issue to our attention.

I’m sorry to hear that the update to v12.0 caused problems on your site. We strive to ensure smooth transitions between versions, and I’d like to help resolve this for you.

To better understand what might have caused the issue, could you please provide some additional details?

1. What version of WordPress are you currently using?
2. Did you notice any specific error messages or logs when your site broke?
3. Can you share any server details (PHP version, hosting provider, etc.) that might be relevant?

Once we have this information, we’ll be in a better position to identify the cause and work on a fix.

Thank you for your patience, and we look forward to your response.

Best regards,

Thanks for getting back to me so promptly.

WP V6.6.1

PHP V8.2

Host: Dreamhost

Error: Cookies blocked due to unexpected output (or words to that effect)

This meant that I could not login to my site until I deactivated the plugin via SSH.

Cheers,

Stephen

Hi Stephen,

Thanks for the quick update.

The error suggests there might be an issue with output being sent before headers, which can block cookies and cause login problems.

To help us investigate, could you let us know if:

1. You saw any specific errors in your logs before this happened?
2. There were any recent changes to your site (like new plugins or theme updates)?

We’ll work on identifying the cause and getting a fix out.

Thanks for your patience.

Sometimes repeated with different line numbers but no “error” messages.

I did update another plugin at the same time (just before the lockout) but trial and error excluded it from the issue.

Hi Stephen,

Thanks for sharing the warnings.

It looks like the plugin is encountering some null values where it expects data, which is likely causing the issues you’re seeing. The “headers already sent” warning is also consistent with the login problem.

I’ll start looking into these specific areas to identify the root cause. In the meantime, if you haven’t already, could you confirm if reverting to V11.9.1 resolved all the issues?

Thanks for your help in troubleshooting this. We’ll work on a fix ASAP.

Hi,
I have the same issue with this update on multiple sites.
All are running the latest version of WP, PHP, and hosted on SiteGround.
Sometimes the sites does not come up when typing the URL manually in the URL bar.
Using a link works oddly enough.
/wp-admin/ is not accessible, only a white screen is shown.
No errors are shown.

Rolling back to the previous version resolves this.

Regards

Yes. Downgrading stops the problem

Hi @torkild

Thanks for reaching out and letting us know you’re experiencing the same issue.

It seems similar to what Stephen reported, with sites running the latest WP and PHP versions.

We’re investigating the issue and will work on a fix. In the meantime, rolling back to the previous version is a good temporary solution, as you mentioned.

If you notice anything else unusual or if any error logs do appear, please share them with us.

Thanks for your patience.

Best regards,
Aditya

Just checked the logs for V11.9.1 and the “Attempt to read property “ID” on null” warning is also there in models/metabox.php on line 112 and controllers/blocks-coupling.php on line 702.

Hi Stephen,

Thanks for the follow-up.

The “Attempt to read property ‘ID’ on null” warnings aren’t critical errors, rather more of a heads-up that the code is encountering unexpected data. While they don’t usually affect functionality, I understand they can be concerning.

We’re planning to address these warnings in upcoming releases as part of our ongoing improvements to CSS & JavaScript Toolbox. We’ll make sure to smooth out these issues as we push more updates.

Thanks for your patience and for bringing this to our attention.
