CSS code seems to be missed

Since a while it seems that the CSS code is missing for my matomo dashboard. The reports that I get by email are working correct and also in de MATOMO-app for android everything works fine. What can be the reason and more important, how can I solve it.

thx for a reaction.

Hi @Joppla
Check in the browser console if there is an HTTP error on some CSS files…

Hi,
It is solved, a cookies was blocked by Ghostery (extention for Firefox).
