I found out now! it is the plugin: multifile-upload-field-for-contact-form-7
I followed the instructions like here: https://github.com/sglessard/multifile-upload-field-for-contact-form-7/commit/5f3bcd3935ad08663226497cd38d99cc022ae237 but always the same! The error message now only appears on the contact form on the whole page! but the form will not be sent! I renounce this plugin and contact the owner! But thank you for your support! Great plugin! Great Job (Contact Form 7)!

I have followed your advice. Unfortunately still the same. Even CF7 completely deleted and reinstalled. Always the same

I have never had problems with the update of plugins. I have restored CF7 to version 4.9.2

I do not use Multifile Upload Field for Contact Form 7, Just Contact Form 7 Version 5.0
and have exactly the same problem.
