Hi!
I had a Multisite set up with WP 3.5 and first did the first page http://marius-schuller.de which worked all the time. I had a memcache Plugin activated.
Then I wanted to set up my blog on http://blog.marius-schuller.de which also went ok (because I was logged in all the time).
As I finished the first post and sent it to my friend he said that he is getting an Error:
"310 (net::ERR_TOO_MANY_REDIRECTS)"
I logged out and got it myself. But only for / direct links to Posts still work: http://blog.marius-schuller.de/willkommen-im-jahr-2012/
I have read around the internet and it seems this problem usually occures on the wp-admin sites but not this time.
I first fixed it when I deactivated the memcached-plugin. I tought it was fixed but today I was informed that it's still the same error.
Every time one surfs to either marius-schuller.de or blog.marius-schuller.de one gets redirected to marius-schuller.de/< or respectively blog.marius-schuller.de/< and I have no idea where this comes from.
Edit:
Also this error comes up on pages like http://blog.marius-schuller.de/instapaper-liste/
It all began after I started working on the second site (blog). And with working I mean changing themes / theme-options and settings.
