Hello, I noticed the same problem on 2 of my websites today. On both of my websites I use Contact Form 7 plugin and since the latest update, after I press the send/confirm button the wheel keeps spinning and the customer doesn’t know if his message is sent. The messages even though the wheel is spinning non stop, they are sent normally.
SOLUTION: I deactivated the plugin ‘Autoptimize’ in both of my affected websites and now the form works perfectly like before. I suspect something with the cache is affecting the Contact Form 7. I hope my solution helps someone else out there. If you don’t have Autoptimize installed then maybe it’s another caching plugin that does the damage.
Before the final solution and finding what was the problem I deactivated every single plugin and it was only Autoptimize that interfered. Maybe with a next update from them it will be fixed without having the plugin deactivated.
The plugins that I use in the 2 affected websites are different from one another and with different themes installed. The only common things are these 2 plugins.
PS. Maybe if there was a way excluding the contact form 7 plugin from caching plugins would also be a solution. But I don’t know how to do this.
