      Hello, I'll try to keep this short. I've been building a Wordpress site. Yesterday, nginx was failing to start and kept throwing errors about config files (which I haven't touched). It started randomly so I took down the post. Now it won't start again. I've attached the errors below. Do I have to do a clean install and migrate the data over? I appreciate any help you can provide.

      I can't figure out what the issue is. For example, the duplicate location error. I would comment out the code and try again. Then it throws another error, and another one after I fix that. It threw errors about lines in the wpsecure conf file and php-wpsc. I've never touched these files so I don't know how something broke. The only thing I have done that I think could have possibly contributed to this was installing a WP Security plugin. I know that it modified my htaccess file, which I reverted back to the original with no success. Again I appreciate any help you can provide, this is very frustrating.

    clue is this your nginx vhost /usr/local/nginx/conf/conf.d/mew.com.conf has duplicate location / {} context configurations.

    You should ensure you only have one location / {} context. Centmin Mod nginx vhost created already have one configured so whatever rules you want to add should be added to the existing location / {} context rather than creating a 2nd copy of the location / {} context.

    Nginx 1.21.x

    Now one possible reason for duplication location / {} context that isn't your fault is if on Centmin Mod 123.09beta01 or newer i.e. 124.00stable or 130.00beta01, you may have ran into the new tools/autoprotect.sh cronjob feature outlined at Beta Branch - autoprotect.sh - apache .htaccess check & migration to nginx deny all | Centmin Mod Community Your uploaded scripts may have .htaccess deny from all type files in their directories which may need bypassing autoprotect. In this case you may have a .htaccess in web root of your site i.e. at /home/nginx/domains/yourdomain.com/public/.htaccess. And autoprotect picks that up automatically to add an entry. In that case removing the /home/nginx/domains/yourdomain.com/public/.htaccess file and re-running tools/autoprotect.sh script manually should update that.

    It's a security feature that no other nginx based stack has as far as I know :)

    So instead, all .htaccess 'deny from all' detected directories now get auto generated Nginx equivalent location match and deny all setups except if you want to manually bypass the directory from auto protection via a .autoprotect-bypass file - details below here.

    You can read a few threads below on how autoprotect.sh may have caught some folks web apps falsely and the workarounds or improvements made to autoprotect.sh with the help of users feedback and troubleshooting.
    Check if your nginx vhost at either or both /usr/local/nginx/conf/conf.d/domain.com.conf and/or /usr/local/nginx/conf/conf.d/domain.com.ssl.conf has include file for autoprotect example
    Code (Text):
    include /usr/local/nginx/conf/autoprotect/domain.com/autoprotect-domain.com.conf;

    see if your directory for the script which has issues is caught in an autoprotect include entry in /usr/local/nginx/conf/autoprotect/domain.com/autoprotect-domain.com.conf which has a deny all entry
    Code (Text):
    cat /usr/local/nginx/conf/autoprotect/domain.com/autoprotect-domain.com.conf

    i.e.
    Code (Text):
    # /home/nginx/domains/domain.com/public/subdirectory/js
location ~* ^/subdirectory/js/ { allow 127.0.0.1; deny all; }

    If caught you can whitelist it by autoprotect bypass .autoprotect-bypass file - details below here. So if problem js file is at domain.com/subdirectory/js/file.js then it is likely /subdirectory/js has a .htaccess with deny all in it - make sure that directory is meant to be publicly accessible by contacting author of script and if so, you can whitelist it and re-run autoprotect script to regenerate your /usr/local/nginx/conf/autoprotect/domain.com/autoprotect-domain.com.conf include file
    Code (Text):
    cd /home/nginx/domains/domain.com/public/subdirectory/js
touch .autoprotect-bypass
/usr/local/src/centminmod/tools/autoprotect.sh
nprestart

    it maybe you need to also whitelist /subdirectory then it would be as follows creating bypass files at /home/nginx/domains/domain.com/public/subdirectory/.autoprotect-bypass and /home/nginx/domains/domain.com/public/subdirectory/js/.autoprotect-bypass
    Code (Text):
    cd /home/nginx/domains/domain.com/public/subdirectory/
touch .autoprotect-bypass
cd /home/nginx/domains/domain.com/public/subdirectory/js
touch .autoprotect-bypass
/usr/local/src/centminmod/tools/autoprotect.sh
nprestart

    then double check to see if updated /usr/local/nginx/conf/autoprotect/domain.com/autoprotect-domain.com.conf include file now doesn't show an entry for /subdirectory/js
