I'm stack because all the websites on my Linux Apache2 web server which have a form to fulfil are returning 413 Request Entity Too Large Error only after first fulfil (refresh makes it working). Error looks like:
Request Entity Too Large
The requested resource
/mailman/subscribe/konrad
does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.
Request Entity Too Large
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Here is apache2 error log:

It gives the error on both (one using PHP and second Perl (cgi)) scripts. I'm not using SSL.
