Hello, my XOOPS is installed on webgamebuilder.com

I've moved from phpnuke to XOOPS a few days ago.. and now users can't reply to any posts.. even to new posts..

anyone can make topics..

This is the newest version of xoops..

I've read several posts about this problem, but nobody has a solution that I can find..

go ahead and sign up, then try to reply to a post if you want to check it out..

I have debugging on.. but don't see any errors..

any help would be awsome

Here are some errors I got when I made a new post..

Notice: Undefined index: nohtml in /home/webgame/public_html/xoops/modules/newbb/post.php on line 165

Notice: Undefined index: nosmiley in /home/webgame/public_html/xoops/modules/newbb/post.php on line 166

Notice: Undefined index: icon in /home/webgame/public_html/xoops/modules/newbb/post.php on line 167

Notice: Undefined index: attachsig in /home/webgame/public_html/xoops/modules/newbb/post.php on line 168

Notice: unserialize(): Error at offset 0 of 99 bytes in /home/webgame/public_html/xoops/kernel/configitem.php on line

which it allows me to do.. but maybe these errors are related to why i can't reply to any of the posts
