Wordpress pagination 404 error "/page/2" - what to do?


The problem mainly arises because permalinks set to Custom Structure /%category%/%postname%/. I understand WordPress assumes "page" is a post from the category.

That is totally normal behaviour. If you want to remove category base you will need to write some custom rewrite rules, not simple rules I must say.

Configure category base to . (dot), put this code in the functions.php of your theme, or better in a plugin, and flush the rewrite rules (code from this post in Daily Web Kit):

add_filter( 'category_rewrite_rules', 'vipx_filter_category_rewrite_rules' );
function vipx_filter_category_rewrite_rules( $rules ) {
    $categories = get_categories( array( 'hide_empty' => false ) );

    if ( is_array( $categories ) && ! empty( $categories ) ) {
        $slugs = array();
        foreach ( $categories as $category ) {
            if ( is_object( $category ) && ! is_wp_error( $category ) ) {
                if ( 0 == $category->category_parent ) {
                    $slugs[] = $category->slug;
                } else {
                    $slugs[] = trim( get_category_parents( $category->term_id, false, '/', true ), '/' );
                }
            }
        }

        if ( ! empty( $slugs ) ) {
            $rules = array();

            foreach ( $slugs as $slug ) {
                $rules[ '(' . $slug . ')/feed/(feed|rdf|rss|rss2|atom)?/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')/(feed|rdf|rss|rss2|atom)/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')(/page/(\d)+/?)?$' ] = 'index.php?category_name=$matches[1]&paged=$matches[3]';
            }
        }
    }
    return $rules;
}

Wordpress - Create a Child Theme


How to Create a Child Theme
1.       Create the child theme directory, which will be placed in wp-content/themes folder. The name of your child theme directory is appended with '-child'. You will also want to make sure that there are no spaces in your child theme directory name, which may result in errors.
2.       The next step is to create your child theme's stylesheet (style.css). The stylesheet must begin with the following
/*
Theme Name: Twenty Fifteen Child Theme
Description: Twenty Fifteen Child Theme
Author: John Doe
Author URI: http://example.com
Template: twentyfifteen
Version: 1.0.0
License: GNU General Public License v2 or later
Tags: light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready Text Domain: twenty-fifteen-child
*/
                Note – Template “twentyfifteen” should be same as parent folder name. this is case sensitive. Otherwise you will get the error “the parent theme is missing. please install the x parent theme”
3.       Create a functions.php in your child theme directory. The first line of your child theme's functions.php will be an opening PHP tag (), after which you can enqueue your parent and child theme stylesheets.

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() { wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
?>

where parent-style In your child code, replace the instance of 'parent-style' with 'twentyfifteen-style', like so:
parent_style = 'twentyfifteen-style';

Unable to RDP to Virtual Machine: CredSSP Encryption Oracle Remediation

To resolve a vulnerability issue with Credential Security Support Provider protocol (CredSSP), a monthly Windows update in May was applied which does two things:
1.       Correct how Credential Security Support Provider protocol (CredSSP) validates requests during the authentication process
2.       Change the group policy Encryption Oracle Remediation default setting from Vulnerable to Mitigated.
This RDP authentication issue can occur if the local client and the remote host have differing Encryption Oracle Remediation settings that define how to build an RDP session with CredSSP. If the server or client have different expectations on the establishment of a secure RDP session the connection could be blocked. There is the possibility that the current default setting could change from the tentative update and therefore impact the expected secure session requirement.

Examples:
1.       If the client is updated and you try to RDP to an Azure VM that was not updated, then it will be blocked and see the error message.
2.       If the client is not patched while server is updated, RDP can still work. But the session will be exposed to the attack.
3.       If both client & server are patched with default setting (Mitigated), RDP will work in a secure way.
References:
Resolution/ Fix
Ensure both client & server side have latest patch installed so that RDP can be established in a secure way.
You can find the list of the corresponding KB number for each operating system here: https://portal.msrc.microsoft.com/en-us/security-guidance/advisory/CVE-2018-0886
If you cannot RDP to  VMs from your patched client, we can consider changing the policy settings on the client to temporarily gain RDP access to the servers. You can change the settings in Local Group Policy Editor. Execute gpedit.msc and browse to Computer Configuration / Administrative Templates / System / Credentials Delegation in the left pane:
Change the Encryption Oracle Remediation policy to Enabled, and Protection Level to Vulnerable:

WP Super Cache — Content Encoding Error

if you are getting the below error:












Steps to fix this:

Go to the advanced settings page and make sure compression is disabled. 

 Since the host already ‘gzip compresses’ enabled, asking Super Cache to do that for you again ends up giving out these weird encoding errors.

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

* Please contact the website owners to inform them of this problem.
