New issue / bug?

Where can we see the website in question?

Hi Takayuki!

It’s my personal site, where?there is only one form in use, on this page:
https://www.temporary-url.com/41039

However, it looks like the error is generated on the WP Cron event(s), rather than on any form submit action.

PHP version: 7.4.24
Contact Form 7: 5.5.1
Contact Form DB: 2.8.16

What kind of cron events are they?

No, I just meant that the error does not appear to occur during on a form submission. I just figured it might be the same timing as WP Cron is pinged (i.e. around every 5 mins or so).

What other plugins and theme do you use on the site?

The only other plugin(s) I can see that have a function ‘get_status’ are:

??Updraft Backups

??WPForms

? Redirection

? GiveWP Recurring

??Broken Link Checker

??All In One SEO Pack

And also a similar critical CF7 error:
