DEN this was identified for some people a few days back, apparently you click next to the words as if the box was there (it still thinks it is but you can't see it) - it worked for some, give it a try. You have to tick submit at the bottom of your details page too?
Other people have posted that you click the check box even if it isn't there ie click the space where it might be. Don't know how you're supposed to know where to click but as i said i've seen that mentioned more than once. Try a search on the site.
DEN, why not try what jackdaniels did, when you go into edit profile, at the top where it says 'your avatar is inactive' click just to the left, and hopefully you'll hit where the box should be! and it'll change to 'your avatar is active'.........don't forget to click submit at the bottom of the page if this works.................good luck
Yep once youve gone to Gravatar, come back here...Edit profile, and click just under where it says Your Avatar is inactive...a little dotted box should appear...then go to the bottom and click submit
thats when the image should appear
