Looking at your site, you are an Elementor Pro user. The developer can’t have a conversation with customers here. That’s not permitted for anyone.

For pro or commercial product support please contact the developer directly on their site. This includes any pre-sales topics as well.

As the developer is aware, commercial products are not supported in these forums. I am sure they will have no problem supporting you there.
