 * Try [manually resetting your plugins](https://wordpress.org/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, access your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/),
   or a file manager in your hosting account’s control panel (consult your hosting
   provider’s documentation for specifics on these), navigate to /wp-content/themes/
   and rename the directory of your currently active theme. Hopefully, this will
   force the default theme to activate and rule out a theme-specific issue (theme
   functions can interfere like plugins).

 * Hey James,
 * thank you very much for this quick answer! Unfortunately both solutions didn’t
   work, is there anything else I can try?
 * Best regards,
   Nathan

 * Ok, try [downloading WordPress](https://wordpress.org/download/) again, access
   your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/),
   or a file manager in your hosting account’s control panel (consult your hosting
   provider’s documentation for specifics on these), and delete then replace your
   copies of everything on the server **except** the wp-config.php file and the /
   wp-content/ directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings.
 * If you’d like to manually make a backup of your site first, please follow the
   steps at [https://wordpress.org/support/article/wordpress-backups/](https://wordpress.org/support/article/wordpress-backups/)
 * Some uploaders tend to be unreliable when overwriting files, so don’t forget 
   to delete the original files before replacing them.
