I apologize for my English. I'm from Spain and languages not taught at school. Thanks Google!!! :P
I'm trying to create custom fields in the translation to translate items created by me, but in the section "Settings" -> "Languages" change the selection and select Custom Category, I do not fields appear. I tried to add the file lang3.php, which is the Spanish file, but when I update the website the file is rewritten by Oxwall software. Then I researched and modified the database to add these custom fields so you can translate small portions of the web page added by me. But back to search custom item "Settings" -> "Language" and remain unaccounted for.
How I can create custom fields in a language?
