When I created my first reply comment and submitted, it showed up twice on the page through the AJAX call. It was fine after refreshing the page, so it didn't get submitted twice. It seems to be a bug in the return function. I opened the page from a submitted time link.
Whenever I try to spin 0.4.x up, the following error occurs in the log:
[cluster] Spinning up another process... [cluster] Child Process (*) has exited (code: 8)
What could be the problem?
Clustering wasn't available in 0.4.x I don't think. So either you've got newer files on your server than 0.4.x, or 0.4.x has become self aware and is mimicking the newer models.
Too spooky, hasn't Terminator taught us anything?!
I reinstalled in a new directory and that fixed it.
