How am I suppose to know what you've done, or anyone looking at this thread.
1. You gave no details on the install of the forum. You never once mention it was an upgrade, a fresh install, or whatever.
2. You never mention if you've testing in alternate browsers (which I asked), to see if it's a browser is (IE browser can be fickle)
3. You never mention if you've testing it on alternate machines (which I asked), it could be your machine.
4. As point 1, you never mentioned the method of installation (there are many). You never mentioned if any mods at all were installed, we are not mind readers.
5. You don't even mention which version of SMF 2.0 BETA you are using.
I wont even go into templates files and themes.
Now the time wasted on trying to convince someone to help us, help them means it can take a lot longer to get around to the hundreds of other support topics. If you say 'forget about it', and want to take no further part in troubleshooting. There is little we can do but mark it solved to clear it from our cue.
