Forms cannot be submit

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

Thank you Takayuki for your response

The theme is the Equita

and the plugins:

CF7 Google Sheet Connector
Classic Editor
Conditional Fields for Contact Form 7
Contact Form 7
Elementor
Elementor Theme Core
ManageWP – Worker
Newsletter
ProfilePress
Redux
Safe SVG
Slider Revolution
SWA Import Export Special
TranslatePress – Language by GET parameter Add-on
TranslatePress – Multilingual

Try switching to the default theme and deactivating all plugins excluding Contact Form 7 and Classic Editor.

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

After the check, the problem seems to be caused by the “translatePress – Language by GET parameter Add-on”, yet it is crucial to have this plugin active ??
