Problem with PO/MO in new version — labels but revert to English after saving

Dear Long,

I can't still figure out what could be the problem, but I will take a look on Loco translate. More info:

The MBCPT plugin itself is loading in English (not a big problem for me), but what I refer too is the content of each label. They are also in English, of course, but I can't modify them permanently. Steps:

1. I do create a "Foo" custom post, all OK.
2. I name plural and singular, "Foos" anf "Foo", all OK.

1. I go to CPT labels and change from, for example, "Add new Foo" to "Adicionar Novo Foo". And I change "All Foos" to "Todos os Foos"... And it is ALMOST OK.

The changes are made, the labels are indeed modified, but the text field itself, on the plugin, retains the old value in English. If I need, for some reason, edit the CPT again, I need to rename aaaall labels once more, otherwise the will be re-saved with the original English values the plugin provides.

If I radically change it to any crazy text, it get's saved, but upon entering the CPT's edit screen again, the value will not be there.

But is is strange, because the same problem happened using just free the MB and MBCPT on on a different theme, a commercial one (mine is all custom and I use premium AIO). On both themes I just activate MB's plugins and use a custom code to "boot" the metaboxes (did learn on your old tutorials). Perhaps my custom way of starting MB internals is breaking something?

This is the way I do:

function teialocal_register_meta_boxes() {

        include 'boxes/post.php';
        include 'boxes/page.php';
            
        if (post_type_exists('case'))     { include 'boxes/case.php'; }
        if (post_type_exists('event'))    { include 'boxes/event.php'; }            
            
    return $meta_boxes; 

}
add_filter( 'rwmb_meta_boxes', 'teialocal_register_meta_boxes' );

I will try MB + MBCPT on a default WordPress template to check if it happens there as well.

Thanks!

Hey there!

Just found, inside MB-AIO folder, a fr_FR PO/MO file that contains the strings I look forward to have translated... But I have no idea how to add this and where add this to my Portuguese WordPress. Everything is sooo confusing. I can't even turn off pt_BR global translation (for a test)!

What should I do?
Can someone provide some simple steps?

In time:

LOCO shows me a lot of stuff from MetaboxAIO, but does not show me nothing related to the regular MetaBox base plugin at all.

Another problem found...

You create a CPT, change its labels to anything else than the default. They get saved (but the fields remain in default EN). Then you think, a far as I do not edit it again, its okay...

But then you access the extension to create a taxonomy, and, after creating it, the CPT got its labels all reset to default again.

Oh my.

It's important to note:

All values GET SAVED indeed. The problem is that they does not retain on the fields. If you need to edit your taxonomy or CPT you will need to write all your labels again, except for the first one (as pointed by Cedric), otherwise, on the next save, all will be reverted to English default values.

Thanks guys!
