Can't start apache2

[Jarkko]

I've been struggling with my server (Ubuntu 14.04) running on Plesk 12.5. Recently there's been problems with the server running .php -files. For some weird reason browsers are not been able to show the php files as they should be but instead browser offers to download these files. This happened with two different machines and 3 different browsers. Since this happened to every php file in the server I concluded that the problem has to be in server and not the browser. So by searching solutions from the internet I also tried to follow one particular instruction. Can't really relocate the instructions I was trying to follow but it had something to do with "a2enmod php5" -command. Now apache won't start anymore and I'm trying to plea for help.

Upon "service apache2 start" there's error message: "AH00534: apache2: Configuration error: More than one MPM loaded." And here's some log notes with apache mentioned from /var/log/apache2/error.log -file:

[suexec:notice] [pid 19224:tid 139880209303424] AH01232: suEXEC mechanism enabled (wrapper: /usr/lib/apache2/suexec)

Any help with this problem is appreciated.

Try to fix it with

# plesk repair web

Thanks for the advice Igor. Sadly this really didn't help since trying to repair server-wide configuration parameters does end up with the previously mentioned error message:

Apache is misconfigured. Could you please show me output of following SQL query in Plesk database:

select * from Configurations where status='error';

Here's the output of Plesk database query:

Ok, finally I got it to work. I disabled php5 mod from /etc/apache2/mods-enabled (a2dismod php5) and mpm_event that was making conflicts. After this apache2 service fired up just fine.
