Contact Form 7 Not Showing Success Message

I have a huge problem with contact form 7! When submitting a message, the message is being sent and we do receive it in our mailbox, but however, the sender doesn’t get any notification that the message has been sent (success message isn’t working).. Which is really frustrating and confusing for users, as they think that the message hasn’t been sent!

I solved this issue but i disabled some settings.
First this problem is related with CACHE PLUG?NS!

I use LiteSpeed Cache when i disable this plugin i can get “Success Message” when i send sometihng!

I searched more!

With above settings Contact Form works excellent, there are no error and i can get “successfully send message”

BUT

When i enable JS COMBINE, the sender doesn’t get any notification!

I want to actimate JS Combine but it conflicts with Contact form plugin!

Are there anything to Exclude in Cache plugin?

Thanks
