Often when loading the webpage for the first time, some of the icons aren’t displayed. When refreshing the page a few times, the problem is solved. What could cause this?
First picture shows the problem. Second picture shows the correct version.
We tested your website but never faced this issue. But anyway, it may happen only in two cases: if you have low internet connection speed and font file with icons is not fully loaded or your server returns some accident error when the browser requests this font. It may happen with any files on the website. But again, we didn’t notice such problems on your website.
