Hey Massakid,
I will need access to your WP admin to troubleshoot the portfolio issue – please provide your login credentials by sending an email to support@satoristudio.net (no disclosure guaranteed). I will also look into the import issue once I can see the back-end.
Regarding your second question: please give more details as to what kind of grid you’re looking for – should it contain elements of various sizes or same size, should they align by rows/columns or form a masonry layout, etc. Thanks!
Sincerely,
Andrii / Satori Studio
