Hey. When you import an error occurs.
What could it be?

Is your WordPress setup a multisite?

If so, the allowed upload file types needs to be adjusted to add the json extension as well.

Located within, Dashboard >> Network Admin >> Settings >> Network Settings

I added json to the network site settings but am still seeing the message. Any other suggested fixes?

This does work.

Add define(‘ALLOW_UNFILTERED_UPLOADS’, true);
to your wp-config.php
but, there is a problem in the latest wordpress that requires super-admin privs for it to work.

There’s probably a db entry for file types allowed anyway (well it should to be compatible with standard coding practices) but if you want a quick fix, backup the file *capabilities.php (in the wp-includes directory) and make these changes if you want it to work and are only logged in as admin.

find the unfilter_upload section and change to:

case ‘unfiltered_upload’:
if ( defined(‘ALLOW_UNFILTERED_UPLOADS’) && ALLOW_UNFILTERED_UPLOADS && ( !is_multisite() || is_super_admin( $user_id ) ) )
$caps[] = $cap;
else
/* temporary removed this for work around
$caps[] = ‘do_not_allow’;
and changed to this after comments
*/
$caps[] = $cap;
break;

the wp_config.php change mentioned previously will work after that.

!!Just back up the files first incase you make a mistake!!
