 * Hello.. your plugin is really great!!.. But I have a problem.
 * I have a WP MU site. I developed with Ultimate Fields in my main site and added
   the PHP code to functions file, but nothing happen in the other sites of the 
   network.
 * I tried with the plugin activated throught the network super-admin and throught
   the plugin manager of each site individually.
 * Also I tried importing using the wordpress import tool (xml). Bad idea. The plugin
   break the site. This error show up:
 * Catchable fatal error: Argument 1 passed to UF_Container_Base::add_fields_array()
   must be of the type array, null given, called in ../wp-content/plugins/ultimate-
   fields/settings/setup-containers.php on line 213 and defined in …/plugins/ultimate-
   fields/classes/UF_Container_Base.php on line 154
 * Any idea?
 * Greetings!!
    Rodrigo.

 * Hi Rodrigo,
 * I’m glad that you like the plugin. You’ve caught me in a weak position though.
 * I checked and in both “versions” of the import/export there were issues. First
   I checked the PHP export and I found that I’m checking the wrong variable. I 
   fixed that.
 * Then I tried the WordPress export/import, which had a similar issue. That should
   be fixed too.
 * What I did not manage though, is to raise the fatal error that you are mentioning.
   Would it be too much if I ask you to send me the XML export?
 * As for the fixes above, you can download the development version from [http://downloads.wordpress.org/plugin/ultimate-fields.zip](http://downloads.wordpress.org/plugin/ultimate-fields.zip).
   It should allow you to use the PHP way.
 * Please tell me if you have any other issues or questions.
 * Best regards,
    Rado

 * Rado!.. Sorry the delay..
 * I tried and now work like a charm!!
 * I forgot to tell that XML fatal error happened when I edited a field and save
   it through Ultimate Field panel.
 * Anyway the PHP import/export method is perfect for me, because I will embed the
   plugin to a theme. 😉
 * Thanks for all!
    Greetings!! Rodrigo.
