Hi,
With your child theme, there are a few issues we need you to amend:
1) There are two functions.php files, please merge the second into the first supplied functions.php file.
2) Update store.php to remove any PHP errors and bring up to date with the latest.
Thanks for deactivating your plugins, feel free to activate them.
The original screenshot you posted with the issue does not look to be apparent anymore for me, do you still get the errors?
– We should have an update for Atelier/Page Builder coming out on Monday to improve issues such as this.
Thanks,
David.
