Topic: Icons failure after domain changing

Hi! I have a problem with icons (f.e. the shop cart and favourities, social media, arrows and so on). When WordPress was on the test domain everything looked perfect. When I changed the main domain and set the right one as default (I assigned the WordPress folder to the right domain and changed the home domain in wp-config) some problems with icons showd up. At the moment all icons like shop cart, favourities, arrows, social icons or even icons from visual composer are now displayed as a rectangles. This problem shows up only on the right domain, on the test domain everything looks perfect (but the ftp catalogue is exactly the same, so the path is the same as well), so I’ve came to conclusion that it must be a problem with urls of images. I’ve used two different plugins to update those links/paths but without any result. Today I deleted and reinstaled both, the main and the child template (one after another), but rhe problem remains. What should I do? Please, help.
