Hello Manuele, 

you can use the theme with or without Elementor Pro is not a must. Keep in mind, if you can provide wp admin access we can import demo data built with Elementor free of charge. This will give you a snapshot of our live demo you can start customizing from.

Hi there,

Send us wp admin access if possible (login url, admin username and password) in a private comment.

Hello Manuele,

we will process your ticket today, appreciate your patience.

Hello,

We finished setting up the demo data, please verify.

You need to replace the demo images scattered throughout content with your own, coming from media library. Browsers are blocking them because of the CORS policy.

Hello, 

you simply assign them in portfolio item options (so when you edit the portfolio item in the backend) in the Hero Section tab:

Hello,

If you are using Gutenberg: you have the pop up image block. Alternatively, if you are using Elementor you have the Pop up image widget.

Let me know if you were able to find it.

For example:

Hello, what exactly is the page URL containing the buttons so we can inspect it?

Hello Manuele,

We need to inspect the page containing the button so we can give you a solution that you can later apply to all buttons.

if you can give as at least temporary access in a private comment?
