When I try to log on via Facebook I get an error

When I try to log on using Facebook I get the following error

I was able to log on alliteratively by requesting a password reset and the rest email gave me a link to log on directly bypassing the Facebook part. I’m not sure if I can log on again…

Can you please check to see if this bug is on your side?

I get the same error. I did the same thing and I now I am in have lost my progress on the Drosophila Melanogaster.

Chrome on a chrome book.

Hi Jennifer and William

This problem should be fixed now - please let me know if it still doesn’t work.

We are sorry about the trouble

It works! thanks! But I still seem to have lost the progress on the Drosophila Melanogaster - Difficulty Level 2
