Hi Scott,
Thank you for your answer.
I am not using those plugins. I tried to desactivate some not essential plugins but it is still not working.

Thank you for your answer but which setting page? I am not an IT professionnel.
I have the same problem since 27/8/2020 with the same version 1.6.8, WordPress 5.5 and CF7 5.2.2. It started after an update of the plugins and an upgrade to WordPress 5.5.
I am not using any compression code plugin.
