@vishalrawat, Do you happen to be aware about using Debug Log in WordPress?
What is the WordPress and PHP version on your install?
Thanks, Umesh
Wordpress version : 4.9.1
Php version : 7
Hello there @vishalrawat,
I’m really sorry for the long delay here, somehow we’ve missed this topic.
Is this still an on-going issue in your end?
Using WP 4.9.5 and latest Smush version? Please advise!
Warm regards,
Dimitris
I checked it yesterday. It is still not working.
Hello @vishalrawat
Could you please access your server via FTP, edit wp-config.php file, find a line like
define('WP_DEBUG', false);
and replace it with the following (if the above line doesn’t exist, simply insert next snippet just above the /* That’s all, stop editing! Happy blogging. */ comment)
// 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 doing so, you should reproduce the 502 error, so any additional information will be logged to debug file, so install/activate Smush again and try to bulk smush until you get the error again.
Then upload /wp-content/debug.log file to a service like Dropbox and post the shareable link here in your next reply.
