How to avoid "Listing 1" on all code examples in org2blog export to wordpress?

How to avoid "Listing 1" on all code examples in org2blog export to wordpress?

[Steinar Bang]

Platform: GNU Emacs 26.3 (build 1, i686-w64-mingw32) of 2019-08-29
          Org mode version 9.1.9 (release_9.1.9-65-g5e4542 @ c:/ProgramFiles/emacs-26.3-i686/share/emacs/26.3/lisp/org/)
          Org2Blog 1.1.1

When I export to wordpress I get "Listing 1" on all text or code
examples in the wordpress blog, se e.g.
 https://steinar.bang.priv.no/2019/11/30/rewriting-applications-to-use-pax-jdbc-config-and-liquibase/

Is there a way to lose the "Listing 1" text completely? 

Or failing that: is there a way to increment the number so that they
aren't all "1"?

Thanks!

I haven't been able to remove them from the export, which would have
been my preferred solution, but I have been able to make them not show.

I googled for 'org export "listing 1"' and found a mention of the CSS
class listing-number, so I googled for 'org export "listing-number"' and
found:
 https://github.com/emacs-china/org-mode/blob/master/etc/ORG-NEWS#listings-with-captions-are-now-numbered-in-html-export

So from https://mysite.wordpress.com/wp-admin/ I clicked on
 Appearance->Customize
and then clicked on
 CSS

Then I pasted the following into the text field
 .listing-number { display: none; }
and clicked on the "Publish" button.

And then the "Listing 1" titles were gone (or at least: not shown) in
the blogposts.

The two lines of ox-html.el that produce "Listing 1", are:
 https://github.com/bzg/org-mode/blob/master/lisp/ox-html.el#L2401
and
 https://github.com/bzg/org-mode/blob/master/lisp/ox-html.el#L3487

I think the second one can be made empty by giving the code example an
empty caption (and this is probably also the one hidden by the CSS?)

But I have one case where neither the CSS suppression or an empty
caption works.  It still shows the useless and meaningless "Listing 1".

Very annoying.
