Hello, After updating the software on our site, we are now receiving an error when trying to add or edit custom posts. When we try to add or edit custom posts, the add/edit page shows without the stylesheet and gives this error in the console: “XMLHttpRequest cannot load …/wp-admin/admin-ajax.php due to access control checks.”
I look forward to hearing any suggestions you may have on troubleshooting this issue.
Thank you!
