apache displaying some really strange characters

Question

I have an Apache web server with several websites on it. All websites are OK except for one...

On one specific Drupal website, I have a really strange issue when I browse the site, it displays the following :

I have nothing else than a page full of those special characters...

Does anybody already encountered this kind of issue ?

I spent half of the day on it, so I would love to hear any idea from you guys.

Thanks a lot !

Answer 1

OK, I figured it out.

In Drupal settings, in the performances section, I had "Compress cached pages." checked.

If I uncheck it, it works...

I don't really understand why, but maybe I had two level of compression or something like this.
