Hello Erik.

Unfortunately I don’t want to post this in the public area.

Had the following plugins in use:

• Autoptimize
• WP Fastest Cache
  (Was unfortunately not compatible with my current theme, was my favorite plugin)
• WP Rocket (My current one)

All were or are on the latest versions.

The version of CF7 is 5.4.1

*** What the current plugin manufacturer did: ***

• I deactivated WP Rocket, so it doesn’t cache or optimize any page.
• I changed the value of the WP_CACHE constant to true in the wp-config.php file. This is a WordPress constant that lets WordPress know a caching plugin is used.
• I then used the form, which still had the issue despite WP Rocket being inactive.

The issue isn’t caused by WP Rocket, since that’s disabled.
It is caused by how Contact Form 7 changes the way it behaves when the WP_CACHE is set to true. You are going to face the same issue with any caching plugin.

*** was all that was said ***

EDIT:
oh by the way:

Have also already deleted CF7 and completely reinstalled again. Has everything brought nothing.

***translated with deepl***

Hope it is understandable.
