I have this issue on two different sites: After I published the demo site on its final URL everything works fine - except the webfonts don't show in the editors of LayTheme/LayGridder. I have this issue on one site with LayTheme and on one site with LayGridder.
Any idea why the webfonts don't show in the editors but on the front ends? I can send you login data if you want to have a look at it. Thanks!
EDIT: I just found out that there was a problem with ONE of the website with the text formats and that solved it THERE (the one with LayGridder). The LayTheme website keeps having this issue and there doest seem anything "obviously" wrong with the site...
