Today, during a website update, it was noted there was an issue with the database that required a backup to be restored. The only backup available to get past the issue was from a month ago.
This means if you changed your password on the website (THIS IS NOT A GROUPS.IO ISSUE) then you will probably have to reset it again.
Also, it was necessary to remove the recently installed Calendar software as this contributed to the problem. I will add a replacement as soon as a suitable plugin is located.
if you are a new member or have to reset your password I apologize for the inconvenience. Please let me know if this causes issues for you.
