Whmcs sef URL problem

[Slaweally]

Hello dear friends, After the latest version of Whmcs, I get url conversion errors in the knowledge base and announcements section.
It does not convert Turkish characters, so it makes problems in these daurls. This problem has just started to happen recently and it was not the case in the past.
Also as a suggestion; Is there a possibility to manually adjust the slug part of the content written to the announcement and knowledge base?

I solved the problem using the following configuration for the Nginx server. friends who have the same problem can use the following configuration.

 

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    {{ssl_certificate_key}}
    {{ssl_certificate}}
    server_name www.orneksite.com;
    return 301 https://orneksite.com$request_uri;
}

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    {{ssl_certificate_key}}
    {{ssl_certificate}}
    server_name orneksite.com www1.orneksite.com;
    {{root}}

    charset utf-8;

    {{nginx_access_log}}
    {{nginx_error_log}}

    # Redirect directories to an address with slash
    if (-d $request_filename) {
        return 301 $uri/;
    }

Do not forget to edit the admin panel and site address according to yourself.
