Without the intent to offend you or irritate you but you're an absolutely horrible system administrator if your solution for every problem is to take a backup and reset the whole server to start from zero.

I've done a little more research as this is the only thing I could do without a server at hand and no real knowledge with Apache and Let's Encrypt. I found some interesting topics that might help you to solve the problem.

First: It looks like you're using Let's Encrypt for your SSL with Apache 2 module. At least this is what your vHost website configuration from the error log hints. And in one of these configurations points to another configuration that points to yet another file. And this exact file is in the Let's Encrypt installation directory but on your system it seems to be missing.

I'm not sure how you installed your Let's Encrypt SSL but I guess the guide you used is absolutely outdated and not working like this example: https://community.letsencrypt.org/t/opti...st/36042/3

So what I would suggest you is to use the official CertBot with its official installation documentation and SSL certificate generation guide for Apache 2:
- Debian 8 + Apache: https://certbot.eff.org/lets-encrypt/deb...sie-apache
- Debian 9 + Apache: https://certbot.eff.org/lets-encrypt/deb...tch-apache
- Ubuntu 16.04 + Apache: https://certbot.eff.org/lets-encrypt/ubu...ial-apache
- Ubuntu 18.04 + Apache: https://certbot.eff.org/lets-encrypt/ubu...nic-apache
- CentOS 6 + Apache: https://certbot.eff.org/lets-encrypt/centos6-apache
- CentOS 7 + Apache: https://certbot.eff.org/lets-encrypt/centosrhel7-apache
