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 9+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 4.6.30, well behind 6.8.

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 prevents showing on the navigation menu on some pages when used with Visual Composer.

    Like everyone else, I wanted to speed up my site and deferring javaScript is a must. The problem is this plugin does more damage than it helps. – Stops drop down menus in Avada from working. – Google Maps, broke. – Sliders, some break. ZERO explanation as to how to exclude certain javascript form deferring. Went to the support board, and they help no one. Good idea, but needs allot of work!

    Great! Easy to use if you need to fine tune speed of your web. There is a need to spped up web downloading, after cache you can use this to optimize Javascript download. But it needs fine tuning otherwise you will get some strange results like pages that do not render properly for a few seconds. Always begin by using a cache plugin.

    For instance breaks Ajax in Contact 7. To avoid IMO.

    Okie, so tested this right now with more than 16 different configurations and it works very well. It is the only plugin that actively defers JS. Rest are not as effective. If you are using any Caching Plugin, it may conflict with your website and may break your site. In 16 tests, nothing like this happened. Tested with PHP7 and latest Version of WordPress.

    Hey guys, i was advised to install this plugin but my site is broken. De-activating and deleting it has not helped… Pls HELP how to resolve this? I read an article that I am supposed to delete my cache which -I think- I did but without effect. Perhaps I haven’t done it on the right please. Deaer Plugin support, please help, my site is unusuable at the moment! René

    I had a site running slowly and was told Javascript needed to be deferred. I was hesitant, but the most recent reviews were good. Nope. It made my site slower and key areas on the main page showed up as white boxes. Kept getting errors trying to delete it, took about 4 attempts for it to go away. Too scary/risky for a high traffic site. This topic was modified 9 years, 5 months ago by ESAR.
