Before reading your post I was browsing through different posts and was trying to resolve the above mentioned error message and I have ended up in a blank page error that says[I had disabled the firewall service]

“This site can’t be reached 10.20.0.16 refused to connect.
Search Google for admin plugins
ERR_CONNECTION_REFUSED”

I’m also unable to restart my httpd service, and when I check the status for httpd I get this message

[root@webserver ~]# service httpd status
Redirecting to /bin/systemctl status httpd.service

Do you have any idea what might have gone wrong?

After looking through all the folders and files I came across this

Resolution: Go to /inc/customizer.php file in your theme folder and search for #page-sub-header and change the background color from #fff to whatever color you need.

See Screenshot for details https://snag.gy/yWFjim.jpg

Thank you @sterndata.
SELinux was the issue!! After reading a lot of other posts and blogs came down to this resolution.

Resolution: Enter this command

ls -Z /var/www/html/path_to_your_website_folder/

If your output is as shown below (read, write permissions are only enabled for wp-content folder.)

-rw-rw-r–. apache apache unconfined_u:object_r:httpd_sys_content_t:s0 xmlrpc.php

All you need to do is enable read write for all the other files and directories which can be done using the following command

chcon -R –type httpd_sys_rw_content_t /var/www/html/rr/path_to_your_website_folder/

Now the output should look something like this.

Solution taken from @toddalancox ‘s post. Thank you @toddalancox. You made my day 🙂
Hope this helps someone else too.

I have updated the ownership to apache:apache, but it still shows the same error 🙁

“Downloading update from https://downloads.wordpress.org/release/wordpress-4.9.6-partial-5.zip…

Unpacking the update…

The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

Installation Failed”

Thank you for the help @afterimagedesigns

I did it by reducing the opacity of my background image in Adobe Photoshop.

The directory in which I have my WordPress theme is rr.
My permissions are

/var/www – rwxr-xr-x (owner-root)
/var/www/html – rwxr-xr-x (owner-root)
/var/www/html/rr – rwxr-xr-x (owner-nobody)
/var/www/html/rr/wp-content – rwxr-xr-x (owner-nobody)

When I run this command ps -ef |grep php, its says PHP is running under root user. Also I checked(cat /etc/sysconfig/selinux) SE Linux is in enforcing state, but how do I change them to 755/644??

Hi Steve,

I hosting my site on a Red Hat Linux on which I have set up a LAMP stack server. I read in a blog that changing access permission would fix the file upload error and followed the steps provided in links 1 and 2(mentioned in my question).

I feel the 500 error that I am getting now, is due to the permissions I have set up. I have taken screenshots to show. But can I upload images in this forum or is there another way to show them?
