Try switching to the default theme, deactivating all plugins excluding Contact Form 7, Classic Editor, WordPress Importer and WP Mail SMTP, and clearing all cache data.

Why you are advised to deactivate plugins and switch to the default theme.

Hi @takayukister,

I have checked with deactivating all plugins and then switch to the wordpress default theme and form worked and then i have reactivated all plugins one-by-one still its working but after switching to the my betterstudio publisher theme again i am facing same error on the CF7 forms.

Now what i can do, my theme don’t have support system.

@bhauserdupli Thanks.

I have rollback CF7 5.4 to 5.3.2 and forms are working now.
