XCSEO Pro not producing 404 error
 

We have had XCSEO Pro installed on our sites and we just realized that it is not giving header code 404 when the page was not found. Instead, it is returning header code 302. It is bad to give incorrect header code to search engines. Does anybody know the work around to this problem?

Yes, that's one of the faults with that package - not sure if you know, but the developer has disappeared, and subsequently been banned from the forum. Many people have removed that software - and I suspect that most people using it are not even aware that this is a problem with it.
You'd be best getting rid of it if possible. Hopefully you'll get a response - just giving you a bit of a background on it.

Thanks for the information. I am aware that the developer is gone. I was hoping somebody who uses this mod figure out the solution to 404 error problem. Anybody?

Do you know which file comes up with the 404 error?
If so just add this to the very top of it:

XCSEO does a 301 redirect, followed by a 302 redirect to a error_message.php file which then throws a 404 header, but google registers the 302. The only way to correct this would be to add the php 404 header code and output a message prior to the 302 redirect, but this isn't possible since the code responsible is ioncube encrypted.
