Glad to hear it worked out. Because it might be helpful for other people, what was the problem?
I just forgot to change the paths in the Configuration. Example: First I had this: bla.de/blog/cgi-bin So my comment-box doesn't work, but the other stuff worked, I dunno why. But I thought "Change this path in www.bla.de/blog/cgi-bin" and look: it works!
I changed a few appearances; I'm not sure if that's the reason why the comment system isn't working. It shows, and it resets fine. Before I changed the appearance of the form of the commenting system, it didn't work then either. So I'm really stumped. Please help me.
Yeah, I feel really stupid now. I should have read "The website address of the directory where all your Greymatter CGI files are kept" My greatest apologies for asking a stupid question. Anyway, thank you VERY much for helping me... it worked!
Interesting. I'm having the same problem and it was the website CGI path that was the problem. I changed it to point to the correct place, and saved it, yet when I try to make a comment it still the shows the old location with a 404 error. If I go back to the configuration page, the correct path is shown in the correct place.
