I belong to a general site. it is the social network for the town, nearest us. I put up a photo just a month ago there, no problem. You can go there and see Oreo today!
It is not a "friend" but a "like" site. Basically it is a update of daily social things, pretty landscape pics etc. Some very interesting historical trivia. Kind of FUN!

Today, those icons are not around anywhere! I asked the admin on the site about it and she said that in her experience she has lost "comment" and "like" boxes for DAYS over there. With no solution. Candis suggested closing Firefox and reloading it, but I haven't done that yet. I suspect it is this computer, having a delayed reaction to the trojan removals, etc.
Other things seem better since the "event"... even faster internet stuff and less Google stalling. Once the pic was up, I did make some comments on other posters things, and that worked for me.

My laptop shows the icons in the proper location.

Facebook is so complicated.... that is why I do very little there.
It would drive us both nuts to have a jillion friends and get all those messages! Whew!
