Ok, here are the problems, XOOPS and Opera 7.53 or 7.54(the newer versions), do not work well. I am not sure how to resolve these, so I have to bring it to a higher authority.

1. members page: you can only view the first page in Opera, if you click on "next" or the page number, it does not go.

2. I believe it is a problem with newbb2 or this(xoops.org) web site. Even after I logged in and my id is shown on the Who's Online block, I cannot POST. In the past I was able to speratically by hitting the refresh bottom several times, but today, no matter what I do, it will not allow me to post. I am using Netscape 7.1 to log in and post here.
My own web site is using newbb1, I have no problem to post there using opera.

I'm using Opera 7.54 and I dont have that problem and although I usually use firefox, I do use Opera sometimes and have never had that problem on this site or any other... cant help you sorry.
