[SOLVED] How to fix 500 errors

[pl.zenon]

Ok, as you wrote, I installed mpm worker instead prefork by:

apt-get install apache2-mpm-worker

Debian installed this package and automatically removed apache2-mpm-prefork. I hope I entered a good command and I didn't make mess in apache?

I read that the newest snapshot of mod_fastcgi particullary repair a incomplete headers problem but I don't know how can I update my mod_fastcgi to this snapshot. Could you tell me how can I do it? I wouldn't like to make mess in my system...
