No problem

Just a couple of data points that might or might not be relevant. I thought I would see if opening any of the local backup files would make a difference. Local backups are all continuing to generate as expected, I can see the files from the 3rd and 4th that are on the server, and all the later backup files up to today are there as well.
Opening a backup from a couple of days ago made no difference; clicking 'view' showed that same list of online backups (up to the file dated 4th), publish immediately opened the website and had the same list (data from the file dated 4th).
Next i opened the local copy of the latest backup showing online (the most recent 4th april file); now when i clicked view, it said there were no online backups, and when I published it appeared to take a little longer; and the online view that opened was the one from that date. I went back to my 'current' coollection file, and it showed the same behaviour as before I started experimenting - the 'view' list had all the same files up until the last one on the 4th, and the website had the 'watched' etc data from that date.
Then - I opened a local backup from a day earlier still (3rd of April); now when I clicked view, it again said that there were no online backups saved; publish appeared to take a little longer, and when the website opened it now had the 'watched' etc from that days file (3rd of April data). And now when I clicked on view, it showed one file as being saved online (with the 3rd of April date).
Then finally I opened up my 'current' file again. Now view showed all the files again up to the 4th; clicking 'publish' appeared to be instant rather than taking 2-3 seconds. But, the data on the website was now the data from the file dated the 3rd, not the 4th, even though I could see that the more recent files (from the 4th) were showing on the server.
Anyway - let me know if you want me to try anything else, and I will try it out tomorrow evening....
Thanks,
