Hi @developer543
I hope you are doing well today.
I visited your page and as soon I clicked on the Submit button I see a console error related to this file:
plugins/forminator/build/front/front.multi.min.js
It could be that the last update failed on your site an that file is missing, but I visited this file URL on your site and it loads fine.
In this case, this issue could be a plugin conflict. Would you please run a conflict test? Please deactivate all plugins except Forminator and check if the problem is gone. If so, then enable all plugins one by one and find which one is having a conflict. If there is no positive result, switch to the default WordPress theme like 2019, and see if it works. Before this test, we recommend full site backup or running this test on the staging site.
Kind Regards,
Kris
