Or not. I just tried it on my home test server and the latest IPB 3.1.4 work just fine with Contentteller. Not sure what's wrong with my installation at the office but I will look into it tomorrow morning.

Found the problem in my office install. I installed Contentteller in a subdirectory and didn't set the cookie path, so both Contentteller/IPB used different cookie paths

In the meantime try to remove the ".msfn.org" cookie domain from your IPB configuration. It seems your website generates two different cookies for www.msfn.org and .msfn.org instead of a single one.

I just tried your website and it is working fine for me. I can login with both Chrome and Safari on your frontpage and get logged-in in IPB as well.

I only noticed a small problem in your site_login_user template. Seems like you added a status to show the number of private messages. The link to your private message inbox is broken because of a missing slash. You currently linking to  http://www.msfn.org/boardindex.php?app=members&module=messaging but it should be  http://www.msfn.org/board/index.php?app=members&module=messaging

Look like Invision indeed changed something in their latest version. I am looking into it right now.

You are right. Updated to 3.1.4

CT
Cookie path: empty
Cookie prefix: empty
Cookie name: .msfn.org

IPB
Cookie domain: .msfn.org
Cookie name: empty
Cookie prefix: empty

I assume you mean 3.1.3 or 3.1.4? What is your cookie prefix and path? You find both settings under Manage Forum Integration.

yes, updated IPB to version 3.1.2

Btw sorry for the delay.

I just realized that this topic is 24 hours old. vBulletin send me the topic notification 2 hours ago . It might be better that you open a trouble ticket next time.

Did you changed anything recently?
