Hello Damira,
I have inspected your site and I am seeing some issue in the site. It could be because you are using an outdated Pro theme. Please make sure that you have updated your WordPress core first and that you have the necessary server settings to run the latest versions before you update the Pro theme. Please check this out first:
- Pro Theme 5.1.5
- WordPress 6.xx
- PHP 7.4
You may also go to Tools > Site Health > Info and make sure that there aren’t any issues.
If the updates are not helping in displaying the slider, we would love to investigate your issue further. You can create a secure note in your next reply with the following info:
– Link to your site
– WP login URL
– WP username
– WP password
– WP Administrator Role
– Confirmation that we can access and make changes to your site

Best Regards.
