1. Install MySQL ODBC Connector. Download it here: https://dev.mysql.com/downloads/connector/odbc/ 2. Run ODBC Search for ODBC Data Source, select 32 or 64 bit based on your OS. My OS is Windows 10 64bit, so I select 64-bit. 3. Add a new DSN Click on Add button to add a new DSN select MySQL ODBC Driver Enter parmeters to the screen. In order to complete the PCI compliance requirements the remote MySQL connection to the server's primary IP is blocked. For establishing a remote MySQL connection to a database you have to use the server's secondary IP. The secondly IP is shown on Remote database access hosts screen. 4.

Author information is an important part of a blog, but for some reason you have to hide it. For example, the blog is a result of multiple authors. 1. Simply hide author information using stylesheet. Add custom css (look like the following): .author,.postauthor-container { display:none; visibility:hidden; } .uwp_widget_author_box { display:none; visibility:hidden; } /* UserWP plugin */ 2. Using "Hide/Remove Metadata" plugin 3. Change code The author information is written by theme, so you have to find out the php code location in order to make change. The possible location is on the following files: single.php, content.php, archive.php, index.php, functions.php, template-tags.php For example, in the theme "Twenty Nineteen" the code is on "twentynineteen_posted_by" function in template-tags.php file. Note that, before making any change on the theme code please make a full backup.   Hope this informaiton will help some people :)

There are many ways to improve WordPress performance. But here I would introduce a trick to dramatically improve the page loading speed. Convert to html page As a web page the ultimate content is html code. If we could response in html directly without bothering the server code and database to run the page would be loaded really quick. make sure the web page working as expected use browser developer tool to view the source copy the html source code go to File Manager of the CPanel, manually create folders and index.html file according to the url pathFor example: for url "https://hostlike.com/zh/web-hosting/"create folder /zh/web-hosting/, then create file index.html under the new folder open index.html with file editor paste the copied content to the index.html file save the content. Dynamic content trick If there is dynamic content, e.g. shopping cart item number. We can use JavaScript to update the value. Add the following JavaScript code to the end of index.html content. function getCookie(name) { const value = `; ${document.cookie}`; const parts = value.split(`; ${name}=`); if (parts.length === 2) return parts.pop().split(';').shift(); } var cart_count = getCookie('woocommerce_items_in_cart'); $('.wcmenucart-details').text(cart_count);

The administrator role somehow loss admin privillage, to restore it as an admin, we could update 2 rows information in database easily. The following DML will restore the admin privillage. set @id=1; update wp_usermeta set meta_value='10' where user_id=@id and meta_key='wp_user_level' update wp_usermeta set meta_value='a:1:{s:13:"administrator";b:1;}' where user_id=@id and meta_key='wp_capabilities' The admin role is controlled by user level and capability attributes, and these information are stored in wp_usermeta table. User level: User Level 0 converts to Subscriber User Level 1 converts to Contributor User Level 2 converts to Author User Level 3 converts to Editor User Level 4 converts to Editor User Level 5 converts to Editor User Level 6 converts to Editor User Level 7 converts to Editor User Level 8 converts to Administrator User Level 9 converts to Administrator User Level 10 converts to Administrator Capability: Refer to: Roles and Capabilities for detail information. In wp_usermeta table the meta_value stored as role: Admin:            a:1:{s:13:"administrator";b:1;} Author:           a:1:{s:6:"author";b:1;} Contributor:  a:1:{s:11:"contributor";b:1;} Subscriber:    a:1:{s:10:"subscriber";b:1;}

Gmail allows external users to send email from its SMTP server. You could set it up in gmail settings or google admin settings.

Scenario Certain contents are allowed by specific group of users to access. Membership roles concept With Members plugin, user roles can be managed in dashboard. Role permissions are called capability. The capabilities are defined based on themes and plugins. The following figure shows the basic role capabilities. Solution Add a user role that allows users to access those restricted contents. Steps 1. Members plugin Install plugin called "Members – Membership & User Role Editor Plugin". 2. Setup roles Go to Members on the left menu of Dashboard. Here you could add a new role or edit an existing role, and then assign permissions, which called capability within the plugin, to the role. 3. Add user to a role Go to Users menu, click on the user that you want to edit. Scrolldown to the bottom, the last section is User Roles. Select the role to assign. 4. Restrict page access by role On the page/post editor, scrolldown to the last section "Content Permission", assign page with the role that is allowed to access the page/post. Done. Now you have restrict the page to be accessed only the users with the role.

After applied SSL settings to enforce HTTPS browser starts complaining "Mixed Content: ..." as the image shown bellow. "Mixed Content" warnings occur when an HTTPS page is asked to load a resource over HTTP. Insecure resources are vulnerable to alteration by an active attacker or eavesdropping by a passive attacker, which violates the user's expectation of security for an HTTPS page. Ref: Fixing mixed content for more information. Fix: Change all insured links with "http://" to "https://" on the page. This could a tough work and time consuming. The following is a hot fix, it works very well for me. Hot fix: Add meta content in html head section to allow browser automatically upgrade http to https, ensure loading contents through SSL layer. <meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

The initial version of this threat was uploaded via wp include file called wp-vcd.php. The malicious code is injected into Wordpress core files like functions.php, class.wp.php, post.php, and also injected into WordPress themes, including child theme. It was reported that WP-VCD malware is a malicious code that comes bundled with illegitimate versions of a paid theme/plugin. These pirated themes and plugins incorporate malicious scripts that get inserted once you install them. Once leaked to your website though a nulled theme, it starts spreading to infect other themes on your site and even proliferates to infect every unprotected site hosted on the shared server.
