The real landscape is so diverse it's difficult to test for every situation.
I think it should be mandatory or at least encouraged that each site has a staging server.
Even a PC with a VM would do, or LAs could do it for small schools or those without the resource.
I reckon a lot more issues would be thrown up this way and without the pain of mucking up a live system.
Not that the onus is removed from Capita, but we know some problems are dependent on the setup so we have to do some testing ourselves.
I applied the "new" patch (18205) a little earlier and tried logging into SIMS afterwards, and so far so good! I managed to get further than I was able to after installing patch 18180!
Any news on why only some are affected?
It's silly that I could, well I don't know at the mo', make a change that puts me in the affected group....
