QUESTION Simple but not easy

[Everyone]

anant, all of what you are describing seems to me like a bad/unfriendly server configuration. I run multiple sites on different hosters, free and paid, using both apache and nginx without any problems. The only times I ran into problems was on a free host, which was injecting its questionable code into my pages. There's also the problematic server at my workplace, which is managed by a guy who doesn't really seem to comprehend *nix. Resolving issues in such circumstances is often impossible. Try a different host, or even a LAMP/XAMPP locally before saying that the software is not stable.

I've seen crappy software being released to public. Not looking too far, the latest 0.8 release of this 'doglike animal CMS' tries to use libraries from files which don't exist, which results in a crippled app; and it's no beta - this is something those guys really released as working software.

I can assure you GS is nothing of that sort.
