You will need to update your functions.php file as follows:

In functions.php find this line (line 225 if you haven’t altered the file):

add_action('init', 'minimatica_register_styles');    

and replace it with —

add_action('wp_enqueue_scripts', 'minimatica_register_styles');

AND

Then find this line (line 437 if you haven’t altered the file):

add_filter( 'ext2type', 'minimatica_mime_types' );

which you will replace with —

add_filter( 'ext2type', 'minimatica_file_types' );

After making the necessary changes, save your functions.php file. If you altered the file offline, upload the saved functions.php file to the wp-content>>themes>>minimatica theme folder. Refresh your new post screen and you should be good to go. This worked perfectly for me so hopefully will for you as well.
