Facebook question (what happened here?)...

For many months I've been using FB "as" a page, then posting pics on other people's walls -- no problem.

Then toady, I posted a pic on many walls -- in very QUICK succession (I'm getting better at my little system).

Everything was going fine, but them it all stopped abruptly when I was met with a error msg saying "There was a problem posting this file." (I'm not sure of the exact wording)

Now I can't post any pics -- not even on my own wall. I tried using a different photo -- I also tried not using fb "as" a page + use my "real" fb page -- any way I try, I cannot post a pic at all at this point.

My question is, how long will this sandboxing last? Is it permanent? Am I in danger of being banned? What should I expect to happen? Or is it just a temporary bug that has nothing to do with me at all? -- just a coincidence?

Please advise.

Thanks!

PS: As far as I know, no one has complained about any of my pics I've posted -- in fact, most of the walls I post on, end up LIKING my pic(s) themsleves!
