 * I recently updated my php to version 7.3 and while my website appears to function
   as expected, I am unable to perform updates on the admin side. I see this fatal
   error:
 * Fatal error: Uncaught ArgumentCountError: Too few arguments to function WP_Screen::
   add_help_tab(), 0 passed in /home1/happinb8/public_html/wp-includes/functions.

 * 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. This will force the 
   default theme to activate and hopefully rule-out a theme-specific issue (theme
   functions can interfere like plugins).

 * Thanks for the reply, James. I tried your recommendations but that does not fix
   the issue with accessing the dashboard.

 * 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.
 * Some uploaders tend to be unreliable when overwriting files, so don’t forget 
   to delete the original files before replacing them.
