Hi Nam
Please disable php gettext extension in xampp then try again.
I don't use xampp so don't know if xampp has an option to enable/disable php extension
If it does not have such option then you should disable gettext by edit file php.ini
- Find php.ini on xampp directory, and search for this line: extension=gettext
- Then comment it out by adding the ;
in front to disable gettext module
- If you don’t find the line, you’ll need to add it in (preferrably to the extensions section)
- Finally restart apache then check the language display result.
