If you are eligible to get a refund according to the Envato refund policy then you can request for a refund. Can I Get A Refund is an explanation of the refund policy, requirements, process and a button linking to the refund request form (below the How to request a refund).
I have the same problem.
If you can edit this file with syntax error /thim-core/inc/functions.php via ftp
you just need to delete last comma on line 61, after $image. And everything will work fine.
