Well, since I got Beoworld back on-line with Community Server 2008 on 21st January 2009 we have had a few issues, well actually 32 problems which I have got them down to 5 of which really only one of them is truly critical.
The critical issue was/is that one of the provided upgrade scripts moves all the pictures which were attached to posts to a central file storage area. However only about 5% of the files were transferred correctly, the other 95% had no picture data in the files. So I have been slowly manually transferring these picture files. So if you come across a post with a picture attachment which is not viewable you know the reason why. I do this manual copying of pictures files in small blocks because it is so boring and time consuming.
