Updated what? all the plugins
How? updated by clicking the update button in wordpress dashboard
Delete what? This is from your first post “delete the directory wp-content/plugins/backwpup, then reinstall the plugin.?
What happens? right after I update all the plug ins, then the “Parse error: syntax error, unexpected ‘$value’ (T_VARIABLE) in /home2/sulrah/public_html/uppn.com/wp-content/plugins/backwpup/vendor/aws/aws-sdk-php/src/functions.php on line 36” occurs.
