Today on and off Chrome failed to load direct links to a thread discussion.
I would receive an email notification, click on the link and receive an error like this:
The server encountered an internal error or misconfiguration and was unable to complete your request.
I would copy paste the same link on Firefox and everything worked fine. Odd.
Before this post I went to the Forums home (English) and the forums loaded and now I don't have issues.
I did close the browser and reboot the computer.
Using Chrome 28.0.1500.95
On Mac OSX 10.84
Not sure if any of this is helpful, but I figure it was best to report it.
