How to Fix WordPress Website Shifting When a User Login

To fix the issue of your WordPress website shifting to the left when a user logs in on their phone, you can try the following steps:

1. Clear Browser Cache: Sometimes, the issue may be related to cached data in the user's mobile browser. Ask the users experiencing the problem to clear their browser cache and try accessing the website again.

2. Check Theme and Plugin Compatibility: Ensure that your WordPress theme and plugins are up to date and compatible with the latest version of WordPress. Outdated or incompatible elements can cause layout issues.

3. Mobile Responsiveness: Verify that your theme is mobile-responsive, meaning it adapts to different screen sizes. Test your website on various mobile devices and use browser developer tools to check how it renders on different screen resolutions.

4. CSS Adjustments: Inspect the CSS of your website and look for any specific styles applied when users log in. Check if there are any media queries that may affect the layout for logged-in users on mobile devices.

5. Child Theme: If you made customizations to your theme's CSS, make sure you did it using a child theme. Directly modifying the main theme can lead to issues during updates.

6. Mobile-Friendly Plugins: Consider using plugins specifically designed to enhance mobile responsiveness and usability for WordPress websites.

7. Debugging: Enable WordPress debugging to see if there are any error messages or warnings related to the issue. This might help identify the root cause.

8. Reach Out to Theme/Plugin Support: If the problem persists, contact the support forums or help desks of your theme and relevant plugins for further assistance.

Always remember to create a backup of your website before making any significant changes to avoid potential data loss.
