Seafile 7 upgrade - icons are missing

Just upgraded my Seafile CE from 6.3 to 7.0.2 and noticed some icons dont show up properly. I restarted the server (Ubuntu 18.04) and still no effect

attaching a screen shot of the problem

any ideas as to how to solve this

did you try to clear the cache of your internet browser

:man_facepalming: thank you that did the trick… i restarted the browser earlier and thought that would solve the problem
