Sorry about that!
Could you add the following to your site’s wp-config.php file, so we can find out more about what’s causing the error?
define( 'WP_DEBUG', true );
if ( WP_DEBUG ) {
@error_reporting( E_ALL );
@ini_set( 'log_errors', true );
@ini_set( 'log_errors_max_len', '0' );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
define( 'CONCATENATE_SCRIPTS', false );
define( 'SAVEQUERIES', true );
}
Your wp-config.php
file may already include a line that says “define(‘WP_DEBUG’, false);”. You can remove it, and replace it by the code above.
Once you’ve done so, you can try to update again. If the error appears again, check the wp-content/debug.log
file for errors, and paste the results here. You can then replace define('WP_DEBUG', true);
by define('WP_DEBUG', false);
in the code above.
Thanks!
