I am having the exact same problem however, I just now had to create a user name and the captcha worked just fine. It must be unique to Yahoo Groups. I've been trying to get in a group for 3 days and no luck. I REALLY hope somebody comes up with an answer soon.
Having the same issue. Have tried multiple browsers too. How will Yahoo know they have an issue? I don't see a way to contact them directly! Very frustrating!
I cannot find any way to contact them either to alert them to the issue. I tried tweeting at YahooCare, so maybe if enough people do that? Or hopefully someone on these boards knows of a way to alert them.
facing captch images not displaying words or number to join the group tried multiple browser
Same problem. Multiple browsers. Multiple devices. Multiple networks. Won't display the captcha or play the audio one at all.
I'm having this problem too and can't find any way to speak to a person at Yahoo...so frustrating.
