I have the same issue, but now using 4.1 or 4.2, even on fresh installs, I think a library is the problem but server logs are not helping.

I also have a similar issue with Laravel 5. Here is a link for details on StackOverflow http://stackoverflow.com/questions/29292650/anyone-succeeded-to-install-laravel-on-apache2-with-fcgi

Here is a cut and paste:

I have successfully installed Laravel on Apache2 with php as a module. The instructions are simple. However, when I try with fcgi it does not work. So it has to do with the server configuration. After I visited http://<mylaraveldomain> (domain not public), I looked at /var/log/apache2/error.log and got this error message

[Thu Mar 26 22:52:34.012794 2015] [fcgid:warn] [pid 30834] (104)Connection   reset by peer: [client 65.92.253.153:7785] mod_fcgid: error reading data from FastCGI server

I also looked at all other log files in /var/log recently modified after visiting the URL, but no additional useful info was found. Should I look elsewhere? It is not that fcgi is not working, because if I put a file test.php in laravel public folder I can read it fine at the URL http://<mylaraveldomain>/test.php. Is there some special configuration settings to make laravel works with fcgi ? It is possible that it is specific to my installation of fcgi. So, I would like to know if others have succeeded to install laravel with fcgi on apache2. I am on Ubuntu and I made a recent apt-get upgrade.
