I tested your actual consolidated apache config that you've posted. The only thing I changed was the directory location of the SSL Certificate file. I'm still not seeing error like what you have posted. So about the only thing I can think of is that this is an SSL Certificate issue. I'm noticing that you have your SSL setup to allow for multiple certificates:
I'd like you have to run through the SSL setup one more time, and please follow all steps according to our documentation, particularly the section on generating the SSL Certificate.
I would also suggest accessing the Admin->Reset Security Credentials page and updating the sub-system credentials.
The extra line from the certificate is the main supplier which according to their doc has to be added to make it a valid certificate. We didn't use the own generated one because we used bought ones.
My co-worker checked the settings himself as he has done this many times already and he cant find anything wrong with it so i doubt the conf itself is the problem.
This install has had lots of problems from the start already so my best guess that has todo with it aswell. Is there a way to reset/reinstall the complete nagios without loosing the hosts? I have resetted the credentials again but that didn't fix the problem.
What is so strange is that the status map also decided to quit working even though the only thing i changed was the ssl setting in the cgi file.

Please understand that there are multiple ways to set up SSL and certificates. The way in which we have tested and documented is the way that we can support. You are certainly welcome to set this up through other methods, but we cannot fully support methods that we haven't documented or tested. Strict SSL support was not even supported in Nagios XI until 2011 R1.6.
I have changed the line as requested but it did not fix anything, i still get the same errors.
Just to be on the safe side i decided to install a complete new central because of the static status map problem. However even without anything changed i am getting similar errors even though the machine still has working http and https access.
