Error with apache config and ERR_EMPTY_RESPONSE

Hello well I have this problem for 2 weeks and I can’t find the answer.

First Mojave came with php 7.3 and I need 7.1 so I proceed to install brew and follow this steps.
After install it I make apachectl start and return me this error

httpd: Syntax error on line 68 of /usr/local/etc/httpd/httpd.conf: Cannot load /usr/libexec/apache2/mod_mpm_event.so into server: dlopen(/usr/libexec/apache2/mod_mpm_event.so, 10): image not found

So I continue digging and this is the httpd.conf file

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
# will be interpreted as '/logs/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
# ServerRoot "/usr/local/opt/httpd"
# ServerRoot "/usr/local/var/www"
ServerRoot "/usr"

#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:/usr/local/var/run/httpd

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8080

So I continue by uninstalling httpd from brew and use apache2 from Mojave and restart the apache by apachectl start and make sudo apachectl configtest and it return

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using Brai.local. Set the 'ServerName' directive globally to suppress this message
Syntax OK

So I run a website that works and show the login page. I writed the username and password and after making the post it return

This page isn’t working localhost didn’t send any data.
ERR_EMPTY_RESPONSE

The website works but there is something with the config.
Any Idea?
