 * It can be difficult to code on a mobile device, but when someone like Bcworkz
   is present, he has been quite helpful!
 * There are no JavaScript reporting issues when our website is rendered using Google
   Console Website ( [https://search.google.com/test/rich-results](https://search.google.com/test/rich-results))
   with desktop method, but we run into these two issues when we render using Google
   mobile. Here are the two problems we encountered:
 * Uncaught TypeError: Cannot set properties of null (setting ‘checked’)
 * Uncaught TypeError: Cannot read properties of null (reading ‘style’)
 * Will it be challenging to solve this one?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Frender-mobile-issues%2F%3Foutput_format%3Dmd&locale=en_US)

 * > but we run into these two issues when we render using Google mobile
 * The errors exist regardless of the device or browser.
 * > Uncaught TypeError: Cannot set properties of null (setting ‘checked’)
 * Caused by:
 *     ```wp-block-code
       document.getElementById("switch").checked = false;
       ```
   
 * Because there is no element in your source with an ID of “switch”.
 * The real solution is to fix or remove the JavaScript but if you can’t do that
   for whatever reason, an empty <span> tag with an id of “switch” in your content
   would eliminate the first error without any visible effect to the user:
 *     ```wp-block-code
       <span id="switch"></span>
       ```
   
 * > Uncaught TypeError: Cannot read properties of null (reading ‘style’)
 * Caused by:
 *     ```wp-block-code
       document.querySelector(".site-title a").style.color = '#blank';
       ```
   
 * Because you have no tag in your source with a class of “site-title” followed 
   by any links.
 * Again, the real solution is to remove or fix the JavaScript but if you can’t 
   do that for whatever reason, an empty <span> tag with a class of “site-title”
   with an empty a tag/link in your content would eliminate the error without any
   visible effect to the user:
 *     ```wp-block-code
       <span class="site-title"><a href="#"></a></span>
       ```

 * Hello @anthonybartoli . I believe that adding an empty Span will work great, 
   however the location of these Javascript is my concern. I entirely developed 
   the idea while backing up any adjustments I made to get where I am. I have attached
   the theme in the hopes that a reupload that I will receive from you will simplify
   things.

 * I don’t see the problematic JavaScript in your theme files. I also activated 
   it on a default WP site and still don’t see it when loading the homepage (some
   JS is generated dynamically). It is likely being generated from a plugin.

 * It is most likely coming from [https://wordpress.org/plugins/seo-by-rank-math/](https://wordpress.org/plugins/seo-by-rank-math/).
   If you deactivate that plugin you should see the error go away.

 * I apologies for the delay in responding, however it is comforting to know that
   the javascript issues are not related to the theme. How am I going to use a SEO
   plugin now? What do you recommend I try using Yeost plugin?

 * The Homepage description won’t remain fixed, which is one of the consequences
   I took into account when determining whether to remove Rathmath. It will be good
   to uninstall Rankmath after you help us with a sample that enables us to enter
   the Home description, and has all other pages echo the excerpt (is_single)
 * That way we can proceed and install IndexNow plugin and re-enable Wp sitemap.
