I use Xili-language for a long time, it works very well until yesterday — when I’m doing something, such as start the Jetback, its Mobile Theme etc., the multi-language feature seems suddenly to be partially failed (such as to the theme, the widget titles).
Check the Xili-langrage settings, find this:
CAUTION: no load_theme_textdomain() in functions.php of child theme – review the content of file in the current child theme or leave as is to use only parent theme translation file.
Check the mo/po files, it seems there are no changes.
Try to stop the Jetback but seems no avail.
All plugins etc are up to date, in addition to the theme (mimbo) with my child theme.
…
Please help me, thank you!
