Dear Jesse, ... you are right: I've just applied the snippet you suggested and it's properly rendering. Thank you very much for your time. All the best

Hello Jesse, thank you for the quick reply. Unfortunately pre and code tags are not suitable for my use case (they render the enclosed text into a separate box), so the only way viable to me is adding the filter to disable text formatting. I went to "Appearence" / "Theme Editor" and picked up "functions.php" file. I added the following

add_filter('run_wptexturize','__return_false');

as last line, but the rendering problem is still there.

Am I missing something?
