I notice yesterday that there is a problem tagging lessons. The tagging field does not show up properly as you can probably see in the picture. I have windows 10 and I use google chrome in case it makes any difference. You can barely see it but the box where you insert the tags has shrieked.
I can second that.
Firefox 43.0 on Mac OSX 10.10.5. Set to not keeping anything in cache so it’s not anything left over from a previous session.
Sorry about that! We are already familiar with this issue and we hope to have it fixed soon. I’ll keep you updated.
