In addition to manual validation, there are several automated tools available to help you validate your WordPress website more efficiently. These tools can scan your website and identify any errors or issues that need to be resolved. Here are a few popular automated validation tools:

  • WP Theme Validator: This tool checks the quality and validity of your WordPress themes. It ensures that your themes meet the WordPress coding standards and are free from any major errors or issues.

By ensuring that your website adheres to SEO best practices and accessibility guidelines, you can improve your search engine rankings and make your site more accessible to all users. Here are some tools and resources to help you with SEO and accessibility validation:

By following the validation checklist, utilizing the W3C validators, and using automated tools, you can easily identify and fix any errors or issues on your site. Additionally, incorporating SEO and accessibility validation into your workflow will further enhance the user experience and visibility of your website. Remember that validation is an ongoing process, and it’s recommended to periodically check and validate your website.

    Thank you in advance!

  2. Hello sir. my problem is my when i write article for my blog then posting area is fix. i am not able to write anything. visual option is not working and all option is hide. what i do. please help me

  3. Good day
    I stumbled upon your site looking for answers to fix my broken theme and am not sure if you offer such kind of support?

    I have installed a second theme (landing page) on my domain in a sub folder. Everything worked as expected but then I decided to change the name of the folder and moved the files over and also made all the associated changes in the wp_config.php, index.php and .htaccess files as well as the database in phpMyAdmin and also including the below in the appropriate pages:



    The changes to Site URL showed up in the WordPress dashboard but when I viewed the page it routed to my main website. I then tweaked a few paths and then it displayed an error when attempting to view the site, but at least the URL path in the browser was correct.

    At last I got the page to display, BUT the theme was broken. I then moved all the files back to the previous folder, made all the changes again, but the theme is still broken… Unfortunately I have not made a backup for this installation….

    Your assistance would be greatly appreciated.
