It seems like Polylang is also screwing with my plugin, wp-sync-db, see issue #74 for details.
I have the same problem, except there is no htaccess file in the upload folder. I already fixed one problem with the avatars not displaying anywhere by changing line 603 of user-avatar.php to $avatar_url = $avatar_src;. However, I still have the problem of avatars not displaying in the crop menu (exactly as Stefan-BBSC discribed)…
By viewing the HTML in firebug, I think that it is trying to load the avatar from “http://localhost/wp-uploads/2012/01/32.jpg“. However, I looked in that folder, and the actual path would need to be “http://localhost/wp-uploads/localhost/2012/01/32.jpg“, so whatever code is putting the image in the wrong folder is probably the problem
thanks, invision-studios… this works, except for displaying the image for cropping.
