WP Super Cache on Windows Server 2012 hosting

Hi @rbergonzini
Thank you for your support question, sorry to hear enabling WP-Super-Cache (WPSC) breaks your site.

Does this happen right after enabling WPSC? Or after saving some settings? When you enable PHP error_reporting, and WP_DEBUG, does that provide you with more to go on? Because “goes into error” is too generic as you might have guessed.

Depending on your hosting environment, you can add the following to wp-config.php to enable error reporting:

ini_set( 'log_errors', 'on' );
ini_set( 'error_log', 'd:/path/to/your/website/log.txt' );
ini_set( 'display_errors', 'on' );

Add this somewhere near WP_DEBUG. And don’t forget to enable that as well:

// Enable WP_DEBUG mode
define( 'WP_DEBUG', false );
// Enable Debug logging to the wp-content/debug.log file
define( 'WP_DEBUG_LOG', false );
// Disable display of errors and warnings 
define( 'WP_DEBUG_DISPLAY', false );

Here (https://www.saotn.org/?s=wp-super-cache) I have more tips and tricks about using WP-Super-Cache on Windows Server 2012 and 2016 (IIS 8.5, IIS 10.0)

hello Jan Reilink,
Thank for your reply! WPSC breaks oursite at least we enable it. But now we can perform steps for enable debug and try to execute instruction of saotn web site!

We post an updated feedback as soon as possible!
Thanks a lot!
Best Regards.
