the disallowed_key_characters is back for our site http://www.mercatornet.com.
At least in Mozilla 3.6.8 in Windows 7.
This is really bad, as the site is effectively blocked.
We faced earlier same problem and we received suggestion from u to upgrade the site to EE 1.6.9. Upgrading it to EE 1.6.9 worked for a while, I think. We are facing the issues again. Pls, suggest to get rid from this forever.
Looking forward ur reply very soon.
