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 3.7.41, 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.

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.

    This plugin crashed many functions in my Divi page. The worst thing of it all is that the page did not get restored by neither deactivating the functions nor the whole plugin! Plus, the last support answer is one year old so there was obviously no hope for help. It was the first time ever I had to replay a backup of my site which is absolutely recommended to make before you install this troublesome plugin IMHO. I would warn from using this plugin after my experiences. This topic was modified 9 years, 2 months ago by wpprup.

    Giving it 1 star because it breaks the site, especially the Revslider. Don’t risk.

    you will get a high pagespeed score but some parts of the site brakes and also my site has lower request but loads longer as without plugin. For a small simple site you may use it but for a complex one no chance to use it.
