Apache webserver fails to start: suEXEC mechanism enabled

Warning message

JQuery Cycle must be installed in order to run the slideshow. Please go to Status Report for instructions.

If apache server failed to restart like this :

sudo service httpd restart
Stopping httpd: [FAILED]
Starting httpd: [FAILED]

then you need to check error logs which might be under this directory if you are running CentOS:


inside this directory you will see error_log. Open this file and read last few entries with:

trail -100 error_log

and if you spot that last few entries are like this :

[Fri Apr 14 19:59:25 2017] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

Then probably you have mis-configured your ssl.conf file or its got corrupted. This file can be under directory:


now to fix this error you need to rename your existing ssl.conf file with mv command:

mv ssl.conf ssl.conf.old

and then create one new ssl.conf and put the defaults contents in it from this comment:

or download from attached post and rename from ssl.conf.txt to ssl.conf and save it on your server.

and press :wq to save and quit.

Now restart your apache server to see if problem is gone:

sudo service httpd restart

Stopping httpd: [ OK ]
Starting httpd: [ OK ]
