Answer 1

I read the function and I solve these issues:
1.
$fileLocation = $fileLocation . $fileName;
$fileLocation used to read file, but it's only contained folder name!
2.
$range = str_replace($range, "-", $range);
str_replace replaces "-" character, but didn't update $range
3.
set_magic_quotes_runtime is deprecated, add a check before calling that function!
You can download new code from my github ;)

Answer 2

Get rid of the ?> at the end of the file.
If that doesn't work post the zipfile somewhere where I can see it.
