Blank page on some variable products

If you deactivate Really Simple SSL this problem goes away?

If that is the case, you can add the following code to your wp-config.php, then activate the plugin again. Then check out the result in wp-content/debug.log

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true );
define( 'WP_DEBUG_LOG', true );

That should point us in the right direction.

I don’t know what you are looking for so I’m copy/pasting everything I got from the moment I deactivated then reactivated the plugin:

These errors do not seem related to Really Simple SSL. I notice you have some database errors from Woocommerce, or a Woocommerce related plugin. I would recommend to contact the author about that.

The headers already sent notice is coming from the optinspin plugin. The optinspin plugin author should be able to help you with those notices.

Hello,
Thank you for your help! I deactivated that plugin and fixed an issue I saw thanks to your previous reply and boom, it all worked out again. I don’t why your plugin, while not, being the cause of the bug, reacted that way (I guess it’s because it’s such a good plugin :D) but at least, found a solution ?? Tahnk you so much!!
