Hello,
http://prntscr.com/q3twrp
You disabled Royal core plugin that is required plugin for Royal theme. One of the third-party plugins that you use probably Ketchup Shortcodes Pack causes a fatal error while Royal core plugin is enabled. Because once we disabled all the third-party plugind for test and started to enable them one by one we were locked while enabled that plugin http://prntscr.com/q3u1ou
So, disable that plugin via FTP (rename or remove) and enable all the other plugins that you used. Or provide FTP access to allow me to finish. We don’t have FTP access to your site, so we can’t do this.
Regards
