Biggest opportunity: Swap “button” for “prettify”. “button” isn't earning its slot: you're not in the first 24 results for its own search. “prettify” sits at #16 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active

At least 300 of 21.2K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,767 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 4.9.35, well behind 6.8.

Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

    I liked this plugin very much, but it stopped working after the latest WordPress update. It’s not possible to click on the ‘<>’ button anymore. Now I have to go to ‘code’ and click on “Code highlighter”. Can you please fix this?

    After upgrade wordpress to the latest version, the codes just inserted to article can not be displayed even you still could see the code insert button. But no result after you edit the codes.

    After updating WordPress, the article page can be displayed normally and highlighted, but it cannot be added normally in the background. After clicking on the insertion code, the edit box will not add new code content.

    Worked really well, thanks! The code formatting looks great. Would be nice to easily change the background from black to grey to help mobile users. My only problem is that it does not integrate within Yada Wiki Editor, which is shame as I cannot just add code to Wiki pages. A work around is to go to page source and add CODE , which is a pain.

    Thanks a lot for simple plugin and greatest color scheme. One problem i have is if the line is too long i can’t read it. Developing the scroll button may fix this issue. Thanks.

Readme readiness

1 of 8 pass · checked 25 Oct 2026

Can an assistant quote this readme? Eight deterministic checks over the wp.org listing, no model involved.

  • ! Says what it does Short description is 30 characters, too short to say what the plugin does.
  • ! Has a FAQ Only 2 questions in the FAQ; 3 or more gives an assistant something to match.
  • ! FAQ asks real questions 1 of 2 FAQ entries are headings, not questions ("Installation Instructions").
  • ! Names who it is for Never says who the plugin is for or what they use it for.
  • ! Names what it works with Names no plugin, service or platform it works with.
  • ! Headings and lists 0 headings and 0 lists; assistants quote headed sections and bullet lists, not paragraphs.
  • ! Enough to quote 326 characters of description; under 1,000 there is little to quote.
  • ✓ Tags match the text 4 of 5 tags appear in the text; "codigo" does not.
