Problems with SSI.php, SMF 2.0 RC4

[tonnebonne]

I have a new problem with SSI after upgrading to SMF 2.0 RC4 from 1.1.12.
The problem is that the first time someone visits my homepage, there is a error message. It doesn't seem to cause any real problems besides the error message, but it would be nice to get rid of it.
If the homepage has been visited the problem dissapears for that user.

The error message (in Swedish) is as following.

Notice: SSI.php lyckades inte att ladda sessionen! Detta kan orsaka problem med utloggning och andra funktioner - se till att SSI.php verkligen läggs till före *allting annat* i dina skript! in /home/homepage/public_html/forum/SSI.php on line 188

Freely translated,
Notice: SSI.php didn't succed to load the session! This can cause problems with logging out and other functions - make sure that SSI.php is really placed before *everythig else* in your script! in /home/homepage/public_html/forum/SSI.php on line 188

Hi, welcome to SMF.

One thing to try is to go into the Admin CP> Server Settings > Cookies and Sessions and set the following:

Enable local storage of cookies - unchecked
Use subdomain independent cookies - checked
Use database driven sessions - checked

Thanks for the help.
I tried your idea. Unfortunately, it didn't help me this time.

You can try changing those settings. It might help.

Is this happening with any particular browser?

The problem seems to be there with any browser.
I haven't had any luck changing those settings unfortunately.

Please can you attach the file that's your home page?
