WordPress admin dashboard is not displaying properly on Plesk server: Access forbidden by rule

    The solution works, but the cause might be wrong. We have seen this symptom on several customer installations that were completely fresh installs done by the WP Toolkit. The symptoms start once the security measures are applied. Reverting security measures however do not fix the issue. So probably there is a different cause that is causing this to happen on fresh WP installs.

    Thank you for your message. Sometimes "Disable scripts concatenation for WordPress admin panel" security measure can affect the administrator panel. I suggest checking whether admin dashboard will work with all other measures on except this one.

    I can confirm that this problem appears on fresh Wordpress installs thru Wordpress Kit. The workaround is not a solution, especially since it manifests on shared servers, we need a fix as soon as possible. Is there at least a server wide workaround?

    Had a simular issue with a clients site over the weekend.  No CSS in wp-admin on clean wordpress install + SSL.


    access log;

    "GET /wp-admin/load-scripts.php?c=0&load%5B%5D=hoverIntent,common,admin-bar,wp-ajax-response,jquery-color,wp-lists,quicktags,jquery-query,admin-comments,jquery-ui-core,jquery-&load%5B%5D=ui-widget,jquery-ui-mouse,jquery-ui-sortable,postbox,underscore,wp-util,wp-a11y,dashboard,thickbox,plugin-install,updates,shortc&load%5B%5D=ode,media-upload,svg-painter&ver=5.2.1 HTTP/1.0" 403 591 "https://staging.example.com/wp-admin/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0"

    error log;

    client denied by server configuration: /wp-admin/load-scripts.php, referer: https://staging.example.com/wp-admin/

    Interestingly I was able to FIX the problem by click on WP Toolkit security and applying all security measures except for;

    Disable scripts concatenation for WordPress admin panel

    Turn off pingbacks

    Enable hotlink protection

    Enable bot protection


    All others are enabled and after that I could log into WP dashboard with CSS working.  Bug when security settings are applied for a fresh install?  Hope that helps someone.
