Markdown seems not to work

[obsd-guru]

when i use markdown it seems to be ignored. no tables, no codeblocks. i checked the markdown i wrote against various online checkers and it seems to work just fine. just bashblog seems to ignore it.
a "whereis Markdown.pl" gibts the right path and i tried the test from line 182 to check if its working.
`
$ whereis Markdown.pl
Markdown: /home/markus/bb/bashblog/Markdown.pl

$ Markdown.pl <<< "line 1\n\nline 2\n"

line 1\n\nline 2\n

$ ` seems the Markdown.pl seems to be fine.
