After installing the theme and its child (downloaded from Envato, unzipped in each individual .zip file), I am experiencing some parse errors on .php files I did not touch.

• when there is the sequence $var_name () ?? ' ' ; --> to solve I had to cancel the entire line
• when there is the sequence : array { --> to solve I had to cancel 'array'

these parse errors happened concernign the files:

• social_counter.php
• featured_archive_posts.php
• penci-menu-callback.php
• header_builder.php

to solve for them all I had to modify the files as explained and save a copy in the child theme to prevent theme updates from breaking the site again.

I also am experiencing impossibility to modify pages in Elementor given the attached error (see screenshot attached). The Elementor plugin was installed and activated through the 'suggested plugins' of the theme.
