Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Can you provide us with your following details at https://stackideas.com/dashboard/site so we can better have a check?

1. Your site backend authentication username password
2. FTP access

I've added the details and some notes

Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

It seems like you provided that backend user account do not have superadmin privileges so I can't access your site backend global configuration page.

Because I would like to identify following thing whether got related with this issue or not :

1. .htaccess file
2. or your server mod_security

And we need your site FTP access so we can able to identify this.

I gave you superuser access.

We don't use FTP, I gave you SCP access and some notes on client and port numbers are in the dashboard

It seems like when I switch off this "search engine friendly urls" setting from your site backend global configuration page https://take.ms/cQULmW , it seems I can able to access composer page on frontend.

This let me think that is related with your htaccess, but I realised you do not have any file .htaccess from your Joomla root folder.

May i know how do you setup on the server so that you can able to use this function "Use URL Rewriting" https://take.ms/4UmN0?

Thanks for the pointer Arlex. That setting should actually be off in the Global Configuration, and turning it off fixed the problem. Consider this ticket closed.

UPDATE:
Actually, we would like to pursue this further, as we do want the URL Rewriting On.

To answer your question, the Joomla SEF rules are in the server httpd global configuration, /etc/httpd/conf/httpd.conf

Thanks for updating Michele, glad that your issue is resolved now.
