Hi,I've been searching the internet about it and found that the error was caused by the language pack (pt_PT (European Portuguese). Does this mean your plugin doesn't work with latin characters), I changed the function to '%s' with support for strings.Oldif($res && ($num=db_num_rows($res))) $showing=sprintf(_N('Showing %d help topic', 'Showing %d help topics', $num), $num);Newif($res && ($num=db_num_rows($res))) $showing=sprintf(_N('Showing %s help topic', 'Showing %s help topics', $num), $num);Obs.d - the argument is treated as an
integer, and presented as a (signed) decimal number.
s - the argument is treated as and
presented as a string.
After that working normally.
