Sorry, you need to enable sending referrers, for this feature to work.

I have the blog installed on two sites of mine. I have another user at one and we’ve both been logging in under the same admin data. Is it possible that this is causing a referrer problem? I seem to think so because I’m not having this problem at the site where I’m the only admin login.

I did what the above link told me to do within my browser and it didn’t change anything.

are you running a firewall? if so, turn it off and then delete

Kaltizer, that wouldn’t cause any problems. It’s most likely a browser or firewall issue as the article above details.

But if it is indeed a firewall or browser issue, then why will it work at one site and not the other?

Because of privacy settings.
What is your OS / browser / firewall /security / AV ?

XP Pro/Firefox 5.0, IE 6.0/McAfee Firewall Plus and Anti-Virus. I have a linux box also and I’m going to try with it.

The same thing happened with the linux box and it doesn’t even have a firewall. Could this not be a remote issue, like read/write permissions?

No, it’s got nothing to do with file permissions.
Got a router ? That affect your traffic ?

I have a broadband router. The blog works at one site and not another with the same local computer. If it’s not a remote problem, then why does this happen?

As it has happened on 2 computers, then it would seem that anything they share is the problem, hence my asking about the router.

This is a software problem, and it is between the phone socket and your computer screen. Not what you want to hear, but it’s always been the case so far. I would closely review every running program, particularly in the router.

For some reason you do not seem to notice the largest factor in this problem, podz. I have this blog freshly installed at a personal site. I have this same identical software installed at a site that I maintain for someone. Now you tell me why I can toggle visibility/delete the links on one and not the other. If it’s between the plug in the wall and my puter screen, then why doesn’t the problem happen with both sites?

I do notice.
I can set my security on this computer I am using to allow me to do what I want to my main blog and I can also set it – at the same time – to NOT let me do anything to other blogs I run.

It is a security software issue.

Ok, what do you suggest I do? My router is not setup to be a firewall. It has a firewall, but it is disabled. I have McAfee firewall plus and anti-virus on my XP Pro machine. The router is the DNS server to the XP machine and a Linux box.

I’m not going to suggest anything.
I will see if someone else will. In the meantime, you have tried disabling the firewall completely for the few moments needed to test ? You have added BOTH sites to any and all trusted zones ? You have read ALL the link at the top and tried any other methods too ? And you have searched this forum for solutions too ??
