After update 8.7.0 seven admin theme can't find icons
Suggestions

I see that you are new to the community, so welcome. Here are some suggestions:


Make sure you performed the updates correctly (preferably using composer)


I see that you've already cleared cache (:

See if the files are actually there in your file system.


If you're not getting this problem on your dev env and only getting it on your server, see if the files are getting uploaded properly.
I had a similar problem and the reason was because of a .gitignore entry which was ignoring the icon files, so they were not getting committed and as a result, they were not being uploaded to the server.

If the SVG files exist on your server, see if you can access them by typing an absolute URL to those files


If not, then maybe there's something in your .htaccess or in your server config which is preventing you from seeing SVG files.



If all of the above don't work, please post a comment and I'm sure me / someone else will surely help.
