How do I fix the issue of menu links turning into empty links in WordPress when I don't know where to begin troubleshooting?

If you are not sure where to begin troubleshooting menu links turning into empty links in WordPress, here are a few steps you can take:

1. Check if the menu items are still assigned to the correct page or post. Sometimes, menu items may lose their association with a page or post, and this can cause them to appear as empty links. To check this, go to Appearance > Menus and make sure the menu items are properly linked to the correct pages/posts.

2. Check for any plugin or theme conflicts. Sometimes, a plugin or theme may be causing conflicts that are affecting the menu links. To test this, deactivate all plugins and switch to a default WordPress theme. Then, test if the menu links are working correctly. If they are, gradually activate your plugins one by one, and switch to your theme to identify the one causing the conflict.

3. Check if there are any custom redirects or rules in place. If you have set up any custom redirects or rules, these could be affecting the menu links. Check for any redirects that may be causing the issue.

4. Check for any error messages in the console. Open the developer console in your browser and see if there are any error messages related to the menu links. If there are, these may help identify the cause of the issue.

5. Reach out to your hosting provider or a WordPress developer. If you are still unable to identify the cause of the issue, reach out to your hosting provider or a WordPress developer for assistance. They may be able to help you diagnose and fix the issue.
