I was in the text editor (not visual). Markdown is enabled in the Jetpack plugin.
I’m using “WordPress 4.6.1 running Adventurous theme”. Jetpack v 4.3.1.
I can reproduce this by adding the following line at the top of my post and clicking ‘Preview Changes’:
#sysd=/etc/systemd/system/
NOTE: Not even using back ticks this time…
Error I get on the preview tab:
“Forbidden
You don’t have permission to access /wp-admin/post.php on this server.”
Immediately removing the line and re-clicking ‘Preview Changes’ works as expected.
Thanks,
Jeff
