it may just be me because until today this site wouldn't allow me to post etc.
I had this problem also and am doing this as a test to see if I could post.  I couldn't find a way to contact the admins.
I also had issues with google constantly giving me captchas due to unusual network traffic.  I cleared the cache and ran a bunch of antimalware and adware removal programs.  That didn't help.  I cleared the cache and now all is back to normal.
I use chrome with AdBlock
