All full text loggin screen

Hi everybody.
I’m Absolutely new with Dolibarr. I’m testing it for an association membership option. I installed it in my desktop(Linuxmint 18, Cinnamon 3.0.7, Muffin window manager) from Dolideb without any problem and it seems to runs ok. But, I also installed in a laptop Asus D540S with Linuxmint 18.2, Xfce4, Xfwm4 window manager, also through Dolideb, and what I get when I try to access with localhost/dolibarr is what you can see in the attaches. Nine months ago, user called Genino reported the same isue but had no answer. I’m a very low profile Linux user. It seems something lacks in laptop browser(both firefox).

Thanks in advance.

Pièces jointes :

Consult ‘/var/log/apache2/error.log’ for more information. I guess it is a setup problem with your Webserver.

If it is the IDENTICAL webserver as on the other system, it might be a browser problem.

Do you have Javacript enabled?

Try to start Dolibar in Incognito Window (w/o every extensions) otherwise.

Any changes?
