Hello,
Thank you. Now access works fine.
We have checked your site and see that you already use Royal 3.4 http://prntscr.com/in1fmg
If you want to update it to version 4.2 (latest version). You need to update WooCommerce and WPMl plugin first. Because theme version 4.0 and higher does not support WC plugin version 3.2.x, only 3.3.x versions.
So, update these plugins and reply back. We’ll continue with theme update.
Regards
