@sterndata Is the path of my wordpress install of on the second command /var/www/html?

• This reply was modified 6 years, 2 months ago by Lee.

Is that where you installed WordPress?

@sterndata Unfortunately I am not too sure. Inside the /var/www/html folder, I see wp-content, wp-includes etc. Is this the installation folder?

Yes,

@sterndata I believe it has solved my issue. I can now install/delete plugins while being able to browse all folders in my FTP!

If you don’t mind, I would like to ask you one more question. I was using a plugin that warned me about my schedule tasks not running properly. I installed the WP-Cron Events plugin and sure enough

There was a problem spawning a call to the WP-Cron system on your site. This means WP-Cron events on your site may not work. The problem was: 
cURL error 28: Connection timed out after 3000 milliseconds

How can I remedy this on my Ubuntu server?

Please install the health check plugin and report back its findings: https://www.ads-software.com/plugins/health-check/

So the issue is why your loopback isn’t working.

What do you get if you do

curl -v https://example.com > /dev/null

Why do you have a plugin disabling updates?

@sterndata I assume to change example.com to my domain? If so, it just hangs there, nothing happens. If I use the command using example.com, it resolves just fine.

By the way, all of my plugins (except health check) are disabled. I don’t understand why it says a plugin is disabling updates.

Your domain.

This sounds like an ubuntu setup issue, not a WP issue.

How did you install WordPress?

@sterndata I followed this guide https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-with-lamp-on-ubuntu-16-04

OK, that’s reasonable. Remove the update related define from wp-config.php

Please provide a link to a page on your site. Thanks.

@sterndata I did find a line added by my old host (Siteground):

# Disables all core updates. Added by SiteGround Autoupdate:
define( 'WP_AUTO_UPDATE_CORE', false );

I removed it but I still get

A plugin has prevented updates by disabling wp_version_check()

My website.

leecosta.com points to 24.2.251.228 which points to a comcast address. I presume the server is in your house?*

That it hangs on loopback points to either an error in your router configuration or a networking configuration on your server, happening outside of wordpress.

*Not a good idea. If the server is hacked, then it’s sitting inside your firewall where you probably have lots of systems that trust anything going on on your network.
