I am running the latest version of WP 5.5.1 and WooCommerce 4.5.2 with XStore Core version 3.0.1 and XStore Theme.
I’m not certain what has happened, but now when I go to create a new page (or edit an existing one) I get a blank page. I also get a blank page when I go to the WooCommerce ‘home’ page which is /wp-admin/admin.php?page=wc-admin
It’s quite odd behavior, especially for the WooCommerc home area because the page starts to load, but then when it looks like the DOM is ready, it just goes blank.
I’ve gone through the process of disabling all other plugins, and nothing fixed the issue until I disabled the XStore Core plugin.
