Hi guys
I have a problem and also lack the understanding to put this rewrite rule in place.
I only need to remove these characters from any URL on our website ?rid=

from this:
Code:
https://rpmdigital.co.uk/coffee/?rid=A611F4
to this:
Code:
https://rpmdigital.co.uk/coffee/A611F4
The first section is created by wordpress https://rpmdigital.co.uk/coffee/
and last part is created by an Xmpie system ?rid=A611F4
the 6 digit number is dynamic and specific to making the webpage personalised to them.
I have been told by Xmpie support that this can be done in the wordpress .hatches

We use apache and Wordpress.
The code I have in my .htaccess file on our apache server is this.

PHP Code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase 
/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond 
%{REQUEST_FILENAME} !-d
RewriteRule 
. /index.php [L]
</
IfModule
is it possible to show me the process as i lack experience

Really appreciate some help on this

Kind Regards
Matt
