G'day bigup401,

Some things for you to check:

• The value of "$res->content".
• The value of "$respons".
• "$respons" is a hashref, with a "data" key, whose value is also a hashref, with a "data" key.
• Why you're assigning the same value to "$qu" and "$je".
• Whether you really need to "remove all JSON::XS lines" or does the problem go away if you remove just some; in other words, track down the actual line(s) causing the problem.
• That you are using the strict and warnings pragmata.

Some things you haven't provided to us:

• Sample input.
• Actual output (even if it's "not readable by browser").
• Expected output.
• Error or warning messages (++marto already mentioned this).
• The versions of Perl and JSON::XS that you're using.
• The encoding of your input data. (Have you tried using methods such as ascii(), latin1(), or utf8().)

You could also check whether the JSON or JSON::PP modules have the same problems. Be aware of an incompatibility issue with JSON and JSON::XS.

Providing an SSCCE, that allows us to exactly reproduce your problem, will greatly improve your chances of receiving a succinct answer.
