Issues with Multisite

Hello there,

I’m trying to figure out if geodirectory works with multisite or not.
I’ve installed Genesis theme and child theme frepro but I don’t need those necessarily if they are a problem.

So there is one German site and one English site now. In the menue in wp-admin I see Geodirectory and Places in the menue in the english site, but in the german site there is only Geodirectory but no Places option.

Trying to update sample places in the english site leads to an error, trying to add a new place leads to an error too:

Fatal error: Uncaught TypeError: Argument 2 passed to Mlp_Translation_Metabox::register_meta_boxes() must be an instance of WP_Post, instance of stdClass given, called in /www/htdocs/w0130ba2/zerowaste-guide.com/wp-includes/plugin.php on line 524 and defined in /www/htdocs/w0130ba2/zerowaste-guide.com/wp-content/plugins/multilingual-press/inc/post-translator/Mlp_Translation_Metabox.php:102 Stack trace: #0 /www/htdocs/w0130ba2/zerowaste-guide.com/wp-includes/plugin.php(524): Mlp_Translation_Metabox->register_meta_boxes(‘gd_place’, Object(stdClass)) #1 /www/htdocs/w0130ba2/zerowaste-guide.com/wp-admin/edit-form-advanced.php(323): do_action(‘add_meta_boxes’, ‘gd_place’, Object(stdClass)) #2 /www/htdocs/w0130ba2/zerowaste-guide.com/wp-admin/post-new.php(85): include(‘/www/htdocs/w01…’) #3 {main} thrown in /www/htdocs/w0130ba2/zerowaste-guide.com/wp-content/plugins/multilingual-press/inc/post-translator/Mlp_Translation_Metabox.php on line 102

I have no clue what this means. Any ideas what I can try to make this work?
Thanks!

Best,
Inge
