Hello, dear "user49915":)
Polylang strings, translate what themes and plugins save in the database, you know, in their configuration screen ...
If the placeholder is not on this list, it will be in the php files. To translate this content, you should look in the theme's translation (.po) files and plugins.
( link )
These files are usually located in folders:
1. Themes
wp-content/languages/themes/{nome-do-tema}/{nome-do-tema}-{idioma}.po
2.Plugins
wp-content/languages/plugins/{nome-do-plugin}/{nome-do-plugin}-{idioma}.po
If the file does not exist, you can copy the .po file from the / languages / folder of the theme or plugin and paste it there.
To edit a .po file you can use:
- poedit link (app)
- loco-translate link (plugin)
When you save the file, these tools have created a binary file (.mo) that will finally be read by WordPress, following the path of the folder paths I mentioned.
If you feel curious, the link below has the form that developers do to internationalize their themes or plugins:
