What do you get on your localhost after installing 2.0.11 / 2.0.12? Are there any errors generated on your local instance? Can you please turn on error reporting so that you could see those errors (if there are any?)
Just to report
Same issue here on a local setup from scratch
Dashboard got a error 503 when empty
I added some activities to solve this, but 1 of the 2 profiles of the site is also still having a 503
503 Service Unavailable
The server is temporarily busy, try again later!
Thanks Adrien head up on this, by right if there don't have any stream data, it should show something like this (screenshot : http://take.ms/PFPIt )
And it seems like this issue we never encounter before, is it possible temporary upload your local site to live then start a new thread from our forums and provide us with your site details so we can able to check on this.
You are most welcome. Glad to hear that your issue has been resolved now.
As a gentle reminder, kindly start a new thread if you have any other issue in the future so it will be easier for us to manage your inquiry. I will lock and mark this thread as resolved.
