Me too, it seems like what @gzingh suggested fixed the issue.

For those of you having the same issue, changed from /includes/api/class-endpoint-api.php line from 242 to this seems fixed the issue.

// force evaluate the result
$result = json_decode(wp_json_encode($result));

$data = array(
‘data’ => $result,
‘headers’ => $this->response_headers,
);
\WP_Rest_Cache_Plugin\Includes\Caching\Caching::get_instance()->set_cache( $this->cache_key, $data, ‘endpoint’, $this->request_uri, ”, $this->request_headers );

return $result;
}

Suggest the developer look at this.

I changed this line, and it is fine now.

/classes/wcff-product-form.php

line 944:
if( is_shop() || is_product() || is_cart() || is_checkout() || is_singular() ) {

Remove is_singular()

so it is:
if( is_shop() || is_product() || is_cart() || is_checkout()) {

And it is fine. Somehow the wccpf_opt is not defined somewhere, not sure why.

Sorry, i mean the one in “class-wp-importer” plugin, since we need that to get posterous importer plugin to work.

Briancolinger, Thanks for the posterous importer plugin, however, i discovered there is a small bugs :

It doesn’t work in wordpress 2.9.2, you have to change this line in your plugin file:

require_once ABSPATH . ‘wp-includes/class-http.php’;

to

require_once ABSPATH . ‘wp-includes/http.php’;

As class-http.php is not exist.
