 * Hello,
 * My website was on version 4.41 and when I went to update to version 4.4.2 the
   site crashed and now when I go back to login I get this error message:
 * Fatal error: Call to undefined function wp_installing() in /home/texmex/public_html/
   wp-includes/option.php on line 174
 * Not sure what to do here. I can’t even get to the login page.

 * I’m sorry to hear you are having problems with this.
 * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)(
   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://codex.wordpress.org/FTP_Clients),
   or a file manager in your hosting account’s control panel, 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).
 * If that does not fix it either, make a backup of your files, then try [downloading WordPress](https://wordpress.org/download/)
   again, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients),
   or a file manager in your hosting account’s control panel, and delete then replace
   your copies of everything 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.
