[Resolved] Issues when switching to secondary language

Problem:
"The error "Unknown format specifier 'a'" in class-wp-list-table.php on line 1039 is caused by an incorrect usage of sprintf with '% articles' instead of a valid format specifier. The code is trying to format a string with a number but uses '% articles' which is invalid.

Solution:
The issue primarily arises because “%s aticles” requires the placeholder %s, but in the French translation, it most likely appeared as “% articles”, where the variable %s was missing.

Since placeholders must remain intact for the string to function properly, you need to correct the translation to include the %s placeholder correctly.

Please go to WPML → String Translation, search for "articles" and correct the translation to be “%s aticles”.
