I have just tried this again on the first 2 links and was able to get through though it took longer than normal. Still error message on the activity stream one.

I have created a thread on the Social Strata help forum for this. I think the problem may be with the activity stream as the first 2 pages (which are the same) now includes a summary of the stream.

Ted has confirmed on the Social Strata help forum they are looking into this. It is probable that it is the activity streaming widget which is causing the problem.

I have discovered that clearing my browser cache seems to have sorted out the problem. I also reset my browser to its default state (I use Firefox).
