It seems that file_get_contents function for URLs is disabled on your server. You need to contact your provider and ask to enable this option.
Otherwise, you will need to remove all infoboxes elements from your website that use SVG images. They are a part of our dummy content.
I talked with my provider but they can’t disabled functions on server. I need to remove all infoboxes elements but how can i do that i don’t know. Do you have an article for this?
You need to edit your pages with WPBakery page builder, find Information box elements and remove them or replace images with PNG or JPG instead of SVG.
But it would be much better to enable that function on the server.
