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 4.0.38, 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.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    You will find the settings in your USER Profile! (Not the first section, where I would seach for it…) I’m just curious: Does the plugin submit every post to an external server for spell checking or is this a completely local process?

    Everything worked great but it kept adding ” ” throughout my article’s HTML which I had to go back and delete.

    This screwed up all the code as well as other plugins. It screwed up spacing with a <span> tag listed every other word for nonexistent errors. AVOID THIS PLUGIN!

    Hi Matthew, thanks a lot for making this plugin available, because as you can see English is not my mother tongue and yet an need to write in it. So, thanks a lot for this plugin. I hope my blog will have less spelling errors from now on and less than this review 😉 [ link redacted, please do not post links in reviews ] So thanks again!

    Great to have a non-Jetpack spellchecker and the basic functionality works great. However since 3.9, the spellchecker leaves all kinds of < span class=”hiddenSpellError” > references in the HTML, the moment you switch it on; bloating the code, breaking shortcodes and embeds and much more. Therefore currently unusable unless you remove all of these Spans manually, which is a ton of work as all unknown words are marked as well.

    The plugin stopped working properly some time ago with important erros. It breaks all shortcodes, oEmbed and leave your content full os <span> elements. The problem was posted in the support forum but there is no reply from the author. See https://wordpress.org/support/topic/since-wp-v39-span-classes-are-added-in-the-code
