Nginx rewrite rule doesn't work at Centminmod but it works on Nginx old server

Hello

I have a weird problem helping a friend of me to move to Centminmod.

My friend has on old server (Nginx default installation) and his IPB forum (v3) is at the forum path like this:

and the forum link is:

The index main page work with no issues on the new server.

When you click on forum category or browse for a topic the link turn to:

I don't like that double forum in the link but as he want it as it is i will try to do it...

So on that link i am getting a 503 error.

If i remove manually from the link one of both /forum/ it works so the problem should be the redirect rule....

I did check and got at the old Nginx config the related rule:

Code:

        location /forum/ {
                index index.php;
                try_files $uri $uri/ /forum/index.php?q=$request_uri;
        }

So i add it on Centminmod https config file and restart Nginx and i thought that this should work but no..

It is very crazy as it works on the default Nginx config and not on Centminmod...

Any ideas?

I attach also the old config here....

Thank you

Check attachment please...

It doesn't work

 

When i was read your reply i was 100% that this should fix the problem but not

I place the rewrite rule above the include lines at the config ( i try also above the rewrite rule for main / ) and restart Nginx but it was not working again

Same error ...

I can provide you access if you want to check it....just let me know please...

 

It doesn't work

I did a try to change it to:

try_files $uri $uri/ /forum/$request_uri;

just out of curiosity and now i can see from a 503 error a 500 error....

 

Problem fixed !

For unknown reason the collation of tables was mixed with latin1 and utf8 in the process of backup/restore ...

I convert them to utf8 and all are ok now

Thanks and sorry for the trouble.
