Hi, it´s not the answer but i have the same problems recently: Lot of errors on using PO file

Hi Camilo 

it seems this issue is so common but no luck to find a solution. Have you contact Joget technical support?

Hello, I have not contacted support. However, I am pretty sure that it has to, in my case, have to do with how complete the translation of the chosen language is. In the case of translation into Spanish, the percentage of translation was very low and I believe that within the translation of the different messages there are labels that alter the format. Then a bad translation of this, I imagine, can make the system show bad items that have to do with the design.

Hi, I tried to switch to zh_TW directly in the Settings and it looks fine. The default zh_TW translation seems quite complete, perhaps the one in the community translation site is incorrect.

Hi Anders

My default zh_TW translation at "Manage Messages" page is blank after installed Joget V6

All the following translations of zh_TW  come from "import PO file" action and they looked fine.

Did your joget version include zh_TW translation already after installed? 

Hi there, Yes, they are bundled. You can look into "\apache-tomcat-8.5.23\webapps\jw\WEB-INF\classes" and find some message bundle there that is already loaded in Joget by default. We included, ar,en,hu,ko,ms,th,zh_CN, and zh_TW. The reason why it is empty in "Manage Messages" because it is for after-market (after installation) messages to be loaded after the installations. These entries will be stored in the database rather be in the file system. Thanks. Hugo
