Some category pages fail to display when enter online but nothing wrong run in local env

[yujiahaol68]

Expected Behavior

categories page should work just like category php

Current Behavior

Some categories output like
ERROR: error on line 56 at column 61: PCDATA invalid Char value 8
and some will just show the XML files content
and some categories are OK.

One thing so wired that is it happens only when browse the deploy site and Nothing wrong when under local hugo server -D

Possible Solution

XML encode issue ??

front-format issue ??

// My front-format

1. Go to category linux for ERROR
2. Go to category node for only XML file content without html parsing
