Wordpress 403 forbidden

Moved Wordpress from another server not nginx.
WP-cache is disabled in wp-config.
I was going to install letencrypt but then I read the acme script creates the vhost file so I deleted the vhost file:

[root@1 addons]# rm -rf /usr/local/nginx/conf/conf.d/domain.com.conf
[root@1 addons]# rm -rf /usr/local/nginx/conf/conf.d/domain.com.ssl.conf (just in case)

Now, before proceeding I'd like to get rid of the 403 error. Is there any place where I can find out what's going on?

was getting a 403 error, I noticed there was a htaccess file and I deleted it. Then restarted nginx and now I'm getting a 404 error. There are no plugins installed.

 

OK...started from fresh
Generate Centmin Mod Nginx Vhost - CentminMod.com LEMP Nginx web stack for CentOS http2

I have Wordpress on /domain.com/wp folder. I'm getting a 500 server error (in WP folder only), I think I have to modify vhost file and update the path where Wordpress is located so I did it but still getting the 500 error

error logs

Code:

2017/08/01 01:15:01 [error] 28741#28741: *12 FastCGI sent in stderr: "PHP message: PHP Warning:  Unknown: failed to open stream: No such file or directory in Unknown on line 0

I don't get why I'm getting errors related to the old cPanel path, I already deleted wordfence plugin and don't know where else to look for a solution

 

Honestly eva I do all the possible to resolve the issues myself. I already did that, deleted all plugins and more.
I noticed there is a html file I'm trying to load insiede the wordpress folder but I'm getting a 403 forbidden error. Ownership and chmod are ok

EDIT: vhost file was wrong, finally fixed it after 2 hours
