So, you just updated WordPress to the coolest, latest version; but you can’t access your website, the site is not working properly, or maybe there are errors showing throughout the website.
For the most part, these are issues are caused by a theme or plugin that has not been updated to work with the latest WordPress version or the WordPress version doesn’t support the PHP version running on your server. Another issue could be — and this is my favorite — that your webmaster hacked WordPress, the theme or a plugin.
The ideal solution
The ideal way to fix all these issues is to get the latest version of the plugin or theme; get your hosting company to upgrade the PHP version; ask your webmaster to stop hacking files and to learn the WordPress API.
All the fixes mentioned above take time to implement; so, what do you do to get your website running immediately? You rollback.
Files Backup
If your web hosting company provides a backup or you have a backup of your files, use them to restore your website. The backup will also restore any hacks made by your webmaster. Ask your company if they can restore the files for you or check your hosting administration area, it usually has restoration tools.
