Hi and welcome to WordPress Trac!

Please note that this Trac is used for enhancements and bug reporting for the WordPress core software, not for individual support questions.

I'm assuming your site is working as it should now, and it's likely that the problem was a partial update due to an interruption in the process or incorrect server's setting for files access. In such cases the hosting company is most likely to help quickly and easily, and if not, the next place to ask is the Support forum: ​https://wordpress.org/support/forum/how-to-and-troubleshooting/

Since there is no specific bug report against WordPress Core software, I'm closing this ticket as invalid.
