White screen on my website after WP update

I’m getting the white screen on my website once I updated WP. I get errors and, by the way, I tried to disable plugins that I have, but with no results. How can I fix this? Any help is welcomed. Thank you.

Hey there!

I suggest that you create a new WordPress install on a subdomain so that no one else gets to see this test, use a name like “trial.meditationyoga.in”.
Manually install an old version of WordPress there say ver 4.9.1
In your wp-config.php enable debugging and error logging, details here:
https://codex.wordpress.org/Debugging_in_WordPress
and

So add settings like:
error_reporting(E_ALL); ini_set(‘display_errors’, 1);
define( ‘WP_DEBUG’, true);
define(‘SCRIPT_DEBUG’, true);

Now get this new wordpress to auto update, see what happens, what messages does it give ?
look at wp-content/debug.log to see if anything gets logged there.

Once you have sorted out the problem, apply it to your main site, you can then either remove or disable the trial site.
