Install of GO 4 fails

[render_ender]

Hi,

i'm trying to install on my hostet server GO4. I was running GO3 for long time smoothly.
The install test on the first install page says some warnings like spellcheck but finally it says GO shoul run.
The install process doesn't bring up any errors.
On the last page when i push "Launch GO now" it results in a Browser tab with adress"///".
So looking to the config.php i found out that the install routine did some misstakes. The root was not set to "/" but to "//" so i changed that.
Also the full url link ended with two // instead of one. So i changed them and Groupoffice login screen comes up, but not the right way.
Its just in a certain text-mode - don't know how to describe it. its just plain text instead of all graphical stuff.
So i tried nearly all ideas i found in this forum.
Mayby someone of you an help me out
