It seems that, in part, my progress had been erased. I still have the " badges " and points and all of my profile, but it tells me that I have no goal achieved ; the home page (where all courses are listed ) is not there anymore ; it's really difficult to access the course i was on ( even from the mails of "congratulations " I can't access , I get ERROR 404 ) .
I did nothing on my computer configuration and errors appear to me , i use the same browser and the same connection always .
I alreay tryed cleaning the cache, i logged out form "signing in with google" and signed in regularily... i don't know what else to do...
Can yout please help me?
PS: beyond this drawback, thank you very much there this page to learn something so necessary for the future as programming .
