Contact Form 7 breaks site

Support
#1

Hi

I’m experiencing the same problem as this user: https://theme.co/forum/t/wordpress-6-1-and-critical-errors/101447

However, it not only breaks the preview, it also causes my entire website to display differently:

Working website:

HHHWorkingSite
HHHWorkingSite1000×829 181 KB

Website after activating Contact Form 7:

HHHBrokenSite
HHHBrokenSite1000×664 18.5 KB

Please note:

  • I have checked for compatibility with other plugins. The problem persists, even when ALL plugins are deactivated.

  • I have checked for Child theme compatibility. The problem persists.

  • I can’t revert to PHP 7.4, as this causes a site-wide 503 error.

  • I have removed all instances of the Form Integration element from my pages and footers. The problem persists.

Do you have any further advice for what can be tried?

Many thanks for your help!

Hi @designbythink,

Thanks for reaching out.
There is no specific suggestion except downgrading the PHP version to 7.4 and checking if that resolves your problem. If that is not possible in your live server, please copy your live site to a staging server and try downgrading the PHP version and check if that works.

Thanks
