Loopback-Request Error 401 + updates prevented by disabling wp_version_check()

    Hi Marius,

    I think this is an issue, which you might have heard already a view times and I also tried to follow all the tickets, which described similar, but no success, so I decided to write:

    I have this WP 4.9 issue of the plugin and theme editor not allowing to alter php-files. Due to reccommendations out of the internet I installed the Healt Check and got these 2 errors:

    “Background updates: A plugin has prevented updates by disabling wp_version_check().”

    “Loopback request: The loopback request returned an unexpected status code, 401, this may affect tools such as WP_Cron, or theme and plugin editors.”

    I activated troubleshoot-mode and tried again. Same errors.

    I deactivated trouble-shoot-mode and started testing by step-by-step deactivating all the plugins. Same again. Even when all plugins despite Healt Check were deactivated.

    Concerning the “Loopback”-Issue: I host on a VPS, which is owned by me and which I can configure via WHM/Cpanel however I like.

    But I kept searching and searching the internet for this “401 Loopback”-Error and did find things like, allow furl_open or activate the alternate_cron-feature in wp-config.php. I tried all this stuff, but no success, still the same Loopback and also the wp_version_check() – error.

    So I gave up and hope, you may be able to help me here.

    This is my configuration:

    Hiya,

    I might be able to provide some insights, yes.

    The first thing that strikes me is that your .htaccess file has custom rules in it, would you be able to share those?

    I’m also wondering if you have any kind of access related rules in your vHost configuration for the site (in apache/nginx)?

    Hi Marius,

    this is the .htaccess – file:

    # BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

AuthUserFile "/home/blackstone/.htpasswds/public_html/passwd"
AuthType Basic
AuthName "blackstone"
require valid-user

# php -- BEGIN cPanel-generated handler, do not edit
# NOTE this account's php is controlled via FPM and the vhost, this is a place holder.
# Do not edit. This next line is to support the cPanel php wrapper (php_cli).
# AddType application/x-httpd-ea-php72 .php .phtml
# php -- END cPanel-generated handler, do not edit

    Ahh yes,

    I see that you require Basic authentication to access your site (a prompt for username and password when visiting the site).

    You may be able to work around this with a loopback exception, I don’t know what version your webserver is running, but try adding the following after the require valid-user line:

    
Order allow,deny
Allow from 127.0.0.1
Allow from blackstone.sale
satisfy any

    It may fail though, depending onb what version you are running as mentioned.

    Hi Marius,

    you were completely right. The basic authentication has been the problem.

    I deactivated it and, boom, above error-message disappeared.

    Nevertheless, when I reactivated the basic authentication and inserted your proposed code, the error messages come back again.

    Is there another workaround in the .htaccess or somewhere else, which I can try, as long as the basic authentication is on?

    Best Wishes,

    Johannes

    (@clorith)

    My bad, it should be Satisfy Any, capitalization matters, and I keep forgetting that ??

    Thread Starter decentris

    (@decentris)

    Hi Marius,

    I corrected the capitalizations (also Require was in small letters):

    AuthUserFile “/home/blackstone/.htpasswds/public_html/passwd”
    AuthName “blackstone”
    AuthType Basic
    Require valid-user
    Order allow,deny
    Allow from 127.0.0.1
    Allow from blackstone.sale
    Satisfy any

    But it doesn’t change anything. It only works, when I deactivate the .htaccess-Authentication.

    Maybe the Health Check doesn’t like access-auths. ??

    But never mind, I now know the reason for the Healt Check – Errormessage, which actually is no error.

    Plugin Author Marius L. J.

    (@clorith)

    I’m afraid I don’t know then, the rules should work fine with the proper capitalizations.

    It’s worth noting that this will prevent tools like WP_Cron (scheduled tasks in plugins, scheduled posts etc) from working unless it’s resolved, so the plugin does correctly report it as a potential problem.

    If you don’t use any scheduled tasks, it won’t be a concern though ??

    Hello @clorith Can I use this htaccess because my problem is also similar with this. Do I have to edit or change anything inside the file? TQ

    It doesn’t sound like you have the same problem, I’d suggest continuing our talk in your own topic, as this is someone elses thread and we’re causing unnecessary email notifications to go out ??
