This plugin has begun affecting all posts / pages on my site, for example when I have a role restricted by product tag, the user is unable to access the cart/checkout pages on the site. A 404 error is displayed.
The error only seems to occur when modify query is enabled.
Maybe you can create/share an admin account to your server (WP and FTP), so I could log in and check what’s going on. If that’s possible – my private email is [email protected]. If sharing an account is not an option – please let me know and I will try to solve this remotely, and in that case please copy/paste and send to me all the info from “WooCommerce > System Status” page.
I have exactly the same problem. When “Bulk Settings” section is enabled and at the same time “Modify query” is enabled only the main page can be accessed – when trying to access any other subpage – including cart & account I have message that page does not exist. I tried to edit visibility for each product separately (when Bulk Settings is not enabled problem does not occur), but that does not hide them. WordPress 5.2 (pl_PL), WooCommerce 3.6.2, PHP 7.2.14, IdeaWebServer/0.83.213 (like Apache), MySQL 5.7.22-22-log.
