Hi Rui,
I did what you asked and removed the plugin and all remaining files via FTP.
I also whitelisted the URL wp-admin/admin-ajax.php on my Sucuri firewall
(note that wp-content/plugins/revslider was already whitelisted).
Any other i need to whitelist?
Unfortunately the submenus’s are still not functioning, with or without troubleshooting settings in the slider settings.
Do you see any other options?
Thanks again!
Kind regards.
Jarl
