Site Health Check: Fails for sites with basic auth and php-fpm

[stephankn]

Situation is PHP running as CGI (for HTTP/2) and admin interface is protected by basic auth.

Authentication is not possible, as the password is not available in the environment:

https://core.trac.wordpress.org/browser/trunk/src/wp-admin/includes/class-wp-site-health-auto-updates.php?rev=45275#L100

the reported conclusion "A plugin has prevented updates by disabling wp_version_check()" is wrong.

Code should check at least AUTH_TYPE for "Basic" or GATEWAY_INTERFACE for "CGI/1.1" to output a proper message. Providing a link to the site-check URL with the instruction to click ans look for the result "yes" in the browser would have also helped.

maybe this check could be done on client-side by javascript in the browser?

Hiya, welcome to WordPress trac, and my apologies for the delayed response.

We could absolutely improve the text used for that test, to make it a bit more descriptive, and not directly blame plugins like it currently does (there are many reasons it could fail, as you've mentioned).

I think that this specific scenario is a bit of an edge case, so I'm not sure if adding buttons and asking users to look for words is the right way forward.

As for making the request be a plain ajax call, there's actually a two-fold reason this hasn't been done.

Due to how the update filter is added, it does not exist within a call to admin-ajax.php, and leaving it open to a plain request without going via there leaves it open to unintended information sharing about a potential security issue on a site.

Do you have any suggestions for improving the texts used here to make it bore clear that this may not always be a problem ?
