If you are experiencing an issue with a particular page on the front-end of your WordPress site, but you can still access the WordPress dashboard, there are a few things you can try to troubleshoot the issue:

1. Clear your browser cache and cookies: Clearing your browser cache and cookies can sometimes help resolve issues with website functionality. To do this, go to your browser's settings or options, and look for the option to clear cache and cookies. The exact location of this option will vary depending on the browser you are using.
2. Deactivate plugins: Plugins can sometimes cause issues with website functionality, so you can try deactivating any plugins that may be affecting the page. To do this, go to the Plugins menu in the WordPress dashboard, select the plugins you want to deactivate, and click on "Deactivate" from the "Bulk Actions" dropdown.
3. Change the theme: The theme you are using can also sometimes cause issues with website functionality. You can try changing the theme to see if that resolves the issue. To do this, go to the Appearance menu in the WordPress dashboard, select a different theme, and click on "Activate."
4. Check for conflicts: Sometimes, plugins or themes can conflict with each other, causing issues with website functionality. To check for conflicts, you can try deactivating all plugins and changing the theme to a default WordPress theme like Twenty Twenty-One. If the issue is resolved, then you can try reactivating the plugins and changing the theme one by one to find the one causing the conflict.
5. Check for errors: If none of the above steps resolves the issue, you can check for errors on the page. You can do this by right-clicking on the page and selecting "Inspect" (in Chrome) or "Inspect Element" (in Firefox). This will open the browser's developer tools, where you can look for any errors in the console. If you see any errors, you can try searching for solutions to those errors.
6. Restore a backup: If you have a backup of your site, you can try restoring it to a previous version to see if that resolves the issue. You can do this by going to the Backup menu in your web hosting control panel, selecting the backup you want to restore, and following the instructions to restore it.
