very buggy and hangs

By theozsnowman on May 19, 2023

ran the plugin on quite a few sites and most timeout after a couple of plugins are tested.

Lots of false positives and errors.

surely there is a better plugin out there?

audit requested does not exist

By elffuts on May 9, 2023

Useless! Gives a 404 error on plugins that ARE PHP 8 compatible. and then hangs. I've been waiting 30 minutes for it to unhang, and I finally gave up. It sure would be nice if this thing worked as advertised. Here's what I got:

MaxButtons Pro 9.5.5

Response status: 404

Message: The audit requested does not exist.

Am I supposed to know what that means? How do I fix it? Right now it's completely useless, and it hangs the software -- never goes any farther to get to the rest of my plugins. Not a bit of help as is.

MANY Incorrect, False results - both ways

By dave22n on April 25, 2023

Rates several themes and plugins as compatible, which definitely are not and have crashed under newer PHP versions (Random Text 0.3.0, WP Bakery 6.0.5, Slideshow 2.3.1 (dereg'd since Apr '22)) -- and has rated several themes and plugins as incompatible which seem to work fine under PHP 7.4 previous versions (Duplicator, LayerSlider WP 6.8.2, UpdraftPlus - Backup/Restore 1.23.3, WP Mail SMTP 3.7.0).

So to have false evals of plugins and themes, both directions, makes this a useless tool and a waste of time. It's a great idea of course, but with the errors I've seen it means it can't even be relied upon to give some clues in a PHP problem hunt.

If I'm missing something will happily change my tune -- because like ChatGPT, it sure gives some attractive, confident-looking answers! And linting ought not be so buggy as all this. Truly quite surprised.

Obviously the website's current php is working or the website wouldn't render. But you have no way to check future php versions and website compatibility. I wanted to see if my website would be compatible to PHP 8.0. This plugin redirects you to LocalWP .... whatever that is.

Works as advertized

By Website Rob on April 7, 2023

WordPress 6.2.0
PHP 8.0 and 8.1
PHP CC Plugin 1.6.1

Although plugin page says: "check your site for compatibility up to PHP 7.4!", I found when using the plugin it will automatically use whatever PHP version the site is using--up to PHP v8.0. Tried using 8.0 and then 8.1 but the results showed were still only up to 8.0.

No errors, no problems, just results I could use. Based on screenshots shown on the plugin page, the new interface is very nice, make one choice then go.

This is a no maintenance plugin - bonus!

Delete this please

Misleading piece of Software, very outdated without information before install. Crap

Malísimo desactualizado Very Bad

By chalynas (riveralvarez) on March 2, 2023

Ya no revisa desde la versión 7.4... imposible verificar la 8.1

Not ready for PHP 8

By Elías (EliasgDJ) on February 9, 2023

It just offers 7.x versions to check

Throws error status 0 and hangs

By lcweltman on February 4, 2023

I'm amazed that this is the only plugin recommended to be run before the latest Wordpress PHP update. It says that its not compatible with my PHP 7.2 and clearly that's true. It hangs repeatedly, sometimes throwing a error status of 0.

Stuck to a previuos era, when dinosaurs used to rule the planet.
