Blank page installing OJS 3.0.0

I uploaded my OJS 3.0.0 but when I browse the index page I see a blank page…

When facing a blank white screen, start debugging with this FAQ:

In my error log I see only this:

PHP Parse error:  syntax error, unexpected '{' in 
 on line 10

Ok, I upgraded my PHP version and finally I see the installation page.

Now I see 4 “Strict Standards” warnings. I have to ignore them, I suppose…

Yes, the strict standards warnings will not cause problems for your users.
