Firstly, checking your site I see this right now -> https://d.pr/i/Vc8UUc
Going by what you describe here, clearly you are having server related issues and you need to contact your hosting provider and have them check the server logs as to what is going on.
There is no way that this “Error establishing a database connection” can be update related, it is simply not possible. Why it is not possible is because the WordPress core file -> wp-config.php is what contains your connection info from WordPress to the actual MySQL database and when updating your theme, only the theme files are updated.
The database, stored data and WordPress core file are not touched in any way. Please contact your hosting provider and have them investigate your log files and overall server settings
Thank you kindly
