Not working correctly with mult language

When using multilanguage some labels fields dont display

for example

?option=com_osmembership&view=register&id=2&Itemid=220&lang=es-ES

.file /language/es-ES/es-ES.com_osmembership.ini does exist. Ihave tryed with lang=es, es-ES, es_ES and non of them display correct content

Using Membersip pro 1.6.8, and Joomla 3.3.6 with native multilanguage . Default language is english, and second language is spanish. First language is shown ok.

First, please make sure you setup multilingual feature works correctly on your site. Please make sure that it works for Joomla core and it will work well for Membership Pro

Also, make sure you edit the custom field, look at the Translation tab and translate the custom field to all of your language. If you don't see translation tab, then multilingual feature doesn't setup properly on your site and you need to correct it

Hello

Multilanguage works correctly. I have my website working for a while.
I use core multilanguage.

I have edited the translation, and i do see the translation tab when editing plans. It is just that when switching to other language rather than default one, it wont show.

I have realized that the strings that are not shown are only OSM_*, all others they work. I may give you access offline

solved: my colleague fond the reason. the database wasn't complete. We will fix it ourselves

Dear Tuan,

I have the same problem like Luis Daniel.
I have two menus for the same category (plan list default layout). I made a menu association. Default language is German, second language is English. The english menu doesn't display the plan. See screenshot. The german menu is correct.
Everythinks works well. I can switch from German to English and have no problem.

Is there any setting to do this?
OS Membership Pro Version 1.7.0 and Joomla! 3.3.6 stable

Thanks.
Sigrid
