Unable to start apache2

Question

I use Ubuntu 18.04.

Command sudo service apache2 restart returns an error.

  kurusa kernel: apache2[17035]: segfault at 7f478cc64e00 ip 00007f4788e13fcf sp 00007ffdb66f0620 error 6 in libphp7.0.so[7f4788bc1000+390000]
  kurusa apachectl[17032]: Segmentation fault (core dumped)
  kurusa apachectl[17032]: Action 'start' failed.

These are some lines from journalctl -xe result:

Here is my apache2.conf:

Also the command sudo a2dismod php7.0 returned:

ERROR: /etc/apache2/mods-enabled/php7.0.load is not a symbolic link, not deleting

How can I fix this problem?

A segmentation fault means a bug in an application, in this case `libphp7.0.so`. See https://bugs.php.net/bug.php?id=70380. The [default `php` version for 18.04](https://packages.ubuntu.com/bionic/php) is 7.2. Could you specify why and how you installed PHP 7.0? — Melebius, Dec 19 '18 at 09:14
@Melebius so i just need to install php7.2, enable it and disable 7.0? — Bipa, Dec 19 '18 at 09:15
I think this might be the same issue: https://stackoverflow.com/questions/49439812/apache-not-starting-in-linux-mint — pLumo, Dec 19 '18 at 09:16
@Racoon I’d definitely try to upgrade to PHP 7.2 if it’s possible. — Melebius, Dec 19 '18 at 09:18
@Melebius, i instaled php7.2 and `php -v` says that i have `PHP 7.2.13-1`, so i tried to run `sudo a2dismod php7.0`, but it returned error `ERROR: /etc/apache2/mods-enabled/php7.0.load is not a symbolic link, not deleting` — Bipa, Dec 19 '18 at 09:20
Check the contents of the `mods-enabled` using the command `ls /etc/apache2/mods-enabled`. PHP 7.0 might have been removed automatically while installing 7.2. Can Apache be started now? — Melebius, Dec 19 '18 at 09:31
@Melebius apache unable to start. all php modules from `mods-enabled` are `php5.6.conf, php5.6.load, php7.0.conf and php7.0.load`. But `php -v` still show that php php version is php7.2 — Bipa, Dec 19 '18 at 09:37
Have you the package [`libapache2-mod-php`](https://packages.ubuntu.com/bionic/libapache2-mod-php) installed correctly? I guess only one version should appear in `mods-enabled` at any time. If you want to switch versions, please check https://askubuntu.com/questions/50344/how-to-have-two-versions-of-php-installed-and-switch-easily-between-them. And please [edit] your question to reflect all the details you posted in comments. It helps to keep our Q&A style tidy and could also bring more attention since an edited question gets bounced on the homepage. — Melebius, Dec 19 '18 at 09:48
