一个意料之外的问题发生了。 WordPress.org 可能有问题

Question

I was not able to install plugins in my WordPress site.

I am getting the following error when i try to install a new plugin.But its allowing me to upload a plugin and then to install it.

"An unexpected error occurred. Something may be wrong with WordPress.org or this server's configuration. If you continue to have problems, please try the support forums."

Answer 1

After spending more time is this I have resolved this by looking at

wp-config.php

Make sure this flag is false, if it's true update couldn't be happen

define('WP_HTTP_BLOCK_EXTERNAL', false);

Answer 2

Try to turn SELinux to permissive to see if it was causing the problem.

And to do that open this file:

nano /etc/selinux/config Then change the line SELINUX=enforcing to SELINUX=permissive

Then reboot:

sudo shutdown -r now

this is working on me on centos 8 thank you

Answer 3

To debug this set WP_DEBUG to true in wp-config.

define('WP_DEBUG', true);

In my case this shows a curl error attempting to reach host: api.wordpress.org when loading the add new plugins page.

On my server curl was already installed correctly. You can run this command to install it on Ubuntu:

sudo apt-get install curl

The solution in my case was to restart Apache.

sudo service apache2 restart

After this the plugin page resolved normally.

Set Debug back to false when you confirm everything is working:

define('WP_DEBUG', false);

Steps I would use:

1. Validate that the filesystem allows WordPress to write to the WordPress directories.
2. Validate that you have allowed outgoing traffic in your web server, firewall and internal network.

When I have run to that error it has usually been some misconfiguration in my machine, either denying write access or outgoing network access from the web server processes.

What do your PHP and web server logs have? Is the site on localhost or on a production server?

Answer 6

There are few steps that you can look for: 1)make sure you have sufficient space on your domain 2) try uninstalling all the available plugins one by one and check (eg : plugin like WP Video Lightbox causes issue like this sometimes

3) Disable all plugins and then reactivating them 4)if you are running wordpress on your virtual machine, try ping test on your server side. 5) if nothing works try installing new version of wp

Hope it helps you

Thankyou

Answer 8

I had the same problem on fedora but after searching for a while it seems that SELinux denied permission to make outgoing network connections. You can find evidence of this in /var/log/audit/audit.log. For example: type=AVC msg=audit(1531585576.912:201): avc: denied { name_connect } for pid=802 comm="php-fpm" dest=443 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:http_port_t:s0 tclass=tcp_socket permissive=0

To resolve the problem:

setsebool -P httpd_can_network_connect 1

Now SELinux will permit WordPress to make outgoing network connections to check for updates.
