Still having the problem with new version 4.2.3–en_US. Someone an idea?
The URL change from “www.name.com/folder/wp-admin” to “www.name.com/wp-admin/”.
The problem is that the change leads to errors (page not found) with any menu element in the dashboard (the issue only affects the dashboard, not the page), for example, https://www.name.es/wp-admin/options-general.php. But when I add the folder than it is working fine, https://www.name.es/folder/wp-admin/options-general.php.
