Hello.
I’ve been trying to get Grav working under my Lighttpd 1.4.35 installation for hours and I am still not sure what is wrong.
Every single setup (skeletons, core, core + admin) shows me a blank page when I try to load it in my browser with the page source being nothing.
I checked all the PHP requirements and I have redirects set, PHP errors turned on, but nothing shows up on the blank page.
Figured it out on my own, so just posting solution for others:
Turns out permissions were actually wrong. Not sure why, but global error reports in php.ini wouldn’t click in, so I took a backdoor approach and called index.php from another script, which then told me that index.php can’t make a directory due to permissions.
Some checking (ps aux | grep light, namely) showed that apparently lighttpd daemon wasn’t run by the user I though it was. After chowning the grav_path to the right person, it was all good.
