This doesnt work, i still get the same error. Can you explain why you used this. '##'. (exists($langhash{$1}) ? $langhash{$1} : $1) . + '##'/es It works when I use this: 
use warnings;

## Debug file to be translated
$filetotranslate = "test.txt";

## Debug file with translated from Spanish to English
$fileout3="debug.txt";


open (FILEIN3, $filetotranslate)  or die "Can't open debug file.\n";
open (FILEOUT3, ">$fileout3")  or die "Can't open output file.\n";

$langhash{'dígito verificador incorrecto.'} = 'digit incorrect.';


while ($linein3 = <FILEIN3>) { 
    
if     ($linein3 =~ /##\s*([^#]+?)\s*##/){
if (exists $langhash{$1}){
$linein3=~ s/##\s*([^#]+?)\s*##/##$langhash{$1}##/;
print "$linein3";
}
else {
print "$linein3";
}}}

close(FILEIN3);
close(FILEOUT3);
