Troubleshoot WPMU Snapshot
I am again trying to use a plugin called Snapshot from WPMU.com to create back-ups of my other MultiSite at toni-esl.com. This time I go a 400B back-up using Snapshot, which is supposed to be a full bkup with plug-ins and everything.
WPMU chat support wants me to use debug and run Snapshot again, which I enabled with a plugin https://wordpress.org/plugins/debug/. Here’s how to do it manually:
could you please enable WP_DEBUG and provide us with the output of your debug.log file?
To enable WP_DEBUG, change the following line in your wp-config.php file:
// Enable WP_DEBUG mode
define( ‘WP_DEBUG’, true );
// Enable Debug logging to the /wp-content/debug.log file
define( ‘WP_DEBUG_LOG’, true );
// Disable display of errors and warnings
define( ‘WP_DEBUG_DISPLAY’, false );
@ini_set( ‘display_errors’, 0 );
After that try to take a backup and if it generates any error it will be added to the debug log file, please go to wp-content/ on your server via FTP and download the debug.log file and let us know
