Hi FelixB

Could you validate if apache is running?

Check if there's an error message there: /var/log/sw-cp-server/error_log

Also, did you check on this kb? its probably relevant to your issue -> https://kb.plesk.com/en/118671 or https://kb.plesk.com/en/124377

aaargh.. right know... the config templates are broken...

Error: New configuration files for the Apache web server were not created due to the errors in configuration templates:

the worst. is i didn't make anything is there a possibility to install this new?

You should be able to get the installation GUI with this.
----------
cd /tmp

wget https://autoinstall.plesk.com/plesk-installer

chmod +x plesk-installer

./plesk-installer --web-interface
-------------

if this doesnt work try this:
/usr/local/psa/bootstrapper/pp[whatever version you have]-bootstrapper/bootstrapper.sh repair

[J-F Brouillette]

Can't be sure @ 100% that this will not erase data but you said it was a new install anyway?

 

[FelixB]

If I was you I would contact Plesk support to be sure.
