Folks, I need to apologize for this!!!!
(red face etc)
In our Home Page, we were using a script that never caused any problems. Until we were switched to a new server a while ago. That script was no longer supported on the new server and was causing the ban on the IPs that were requesting it (probably a lot more folks faced this problem, but never bothered to complain!). Code has been changed to remove the script, so you shouldn't have any more problems.
Apologies to all for the inconvenience! I feel so ashamed, even though there was nothing I could do, until you let me know!!!!
Have a great weekend guys and gals!
