This is the case.
Joomla version: 1.5.25, Kunena version 1.7.1, Jomsocial version 2.2.4, SH404SEF version 2.4.3.1014. Module HelloMe from Jomsocial to login.
In SH404 i switched on the 301 redirect www/non-www. That's working fine. I can replicate the problem when I login in IE without using the www. It routes me back to the Jomsocial login page. I can't login at all, not with the HelloMe module, not on the Jomsocial page and also not in the Kunena login. Some of my users say they have to try many times before they finally can login in Kunena.
The strange thing is that when I select "remember me" before I login, everything works fine. For me it's always working in Chrome, even without the remember me option and also after I clean the cache in Chrome. In IE after first wrong try you have to clean the cache before you can login again (with the remember option).
I did a search on google and find one solution from a guy who changed the setcookie setting. He wrote that it is related to the 301 redirect and put a line somewere to let the cookie be valid on domain with or without www. I can't find this article anymore
I know there are a lot of problems with SH404 related to Kunena and also asked them already for help, but they don't answer. But I even don't know if it is related to SH404. Actually I also don't want to switch of SH404 temperaly because I already had to fix many 404 links after I installed it from links kept in google or in my users history. And also not everybody has this problem.
Can somebody point me in the good direction how to use the setcookie option for a www/non-www domain and especially were to put the code? From what I understand I have to put it somewere in php and not in the .htacess...
