Hi! I have created a collection but even though I have no problem saving each items, I can’t upload audios and pictures. I have got a 500 Error.
Hi Marianne,
this error can happen if the name includes characters that are not usual in English.
Also it could happen if the name is too long.
I hope this helps.
Hi Vera! Thanks, but sadly it doesn’t help 
Hi Marianne, I just got the same problem when uploading the audio file for a new lesson: “500 - Server error”
And I don’t receive e-mail alerts… It seems we again exceed space limit.
This problem should now be resolved. Sorry about that. It was the space limit again.
It works perfectly now! Thanks 
Usually there was a message after the import was done and after the lesson was shared. I don’t receive these messages any longer.
I still see these messages. Is anyone else not seeing the green success messages at the top of the page when importing and sharing?
I see them too. I just uploaded two lessons this morning.
Now it works for me too.
