Edit Permalink Structure For Custom Post Type or Modify .htaccess?

Question

I've been trying to find a solution for days now and I am absolutely stumped.

I am putting together a website to list my domain portfolio for sale and I'm using a plugin I purchased to lists the domains. The author of the plugin is nowhere to be found and I only have a basic understanding of PHP.

The plugin lists each domain name as an individual post, but it uses a custom post type which is displaying the post page url as optibrands.com/?mdlp_my_domain_list=znvr-com where znvr.com is the domain for sale and title of the post.

What I want to do is clean up the url by removing /?mdlp_my_domain_list= and having it displayed as optibrands.com/znvr-com or optibrands.com/domain/znvr-com if the former isn't possible.

I tried rewriting the htaccess tons of different ways, but nothing has worked. The closest I've come is adding:

`RewriteEngine On RewriteCond %{THE_REQUEST} \ /+(index.php)?\?mdlp_my_domain_list=([^&\ ]+) RewriteRule ^ /%2? [L,R]

RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^/]+)$ /?mdlp_my_domain_list=$1 [L,QSA]`

This rewrites the urls how I would like, but it creates a redirect loop error.

I have also tried tweaking the plugin's functions PHP, but I'm not quite sure I know what I need to be editing.

These are the pieces of code I think need to be rewritten:

public function filterRewriteRules( $wp_rewrite ) {

                        $base = trailingslashit( $this->rewriteSlug );
                        $baseSingle = trailingslashit( $this->rewriteSlugSingular );
                        $baseTax = trailingslashit( $this->taxRewriteSlug );
                        $baseTax = "(.*)" . $baseTax;

                        $newRules[$base . 'page/(\d+)'] = 'index.php?post_type=' . self::POSTTYPE;
                        $newRules[$baseTax . '([^/]+)/?$'] = 'index.php?post_type= ' . self::POSTTYPE;

                        $wp_rewrite->rules = $newRules + $wp_rewrite->rules;

and/or

public function initialize() {
                                $this->pluginName = __( 'My Domain List', $this->pluginDomain );       
                                $this->rewriteSlugSingular = 'my-domain-list-pro-single';      
                                $this->rewriteSlug =    'mdlp_my_domain_list';                         
                                $this->taxRewriteSlug = $this->rewriteSlug . '/' . __( 'mdlp_categories', $this->pluginDomain );

and/or

public function create_post_type() {
                    $this->get_post_type_labels();
                    register_post_type(self::POSTTYPE, $this->postTypeArgs);                       
                    register_taxonomy( self::TAXONOMY, self::POSTTYPE, array(
                            'hierarchical' => true,
                            'update_count_callback' => '',
                            'query_var'=>true,
                            'rewrite' => false,
                            //'rewrite' => array('slug'=> $this->taxRewriteSlug),
                            'public' => true,
                            'show_ui' => true,
                            'has_archive' => true,
                            'labels' => $this->taxonomyLabels

Edit: Here is the entire contents of the PHP file

If anyone has any idea what I can do to fix this I will be forever grateful, because I've just about given up hope!

Based on your pastebin of the plugin code, the issue seems to be in the registration of the custom post type. The issue is on line 25. "Rewrite" should be set to true.

<?php
                private $postTypeArgs = array(
                    'public' => true,  
                    'rewrite'=> false,                
                    'singular_label' => 'mydomainlist',
                    'publicly_queryable' => true,
                    'show_ui' => true,
                    'show_in_menu' => true,
                    'query_var' => true,                   
                    'capability_type' => 'post',
                    'has_archive' => true,
                    'hierarchical' => false,
                    'menu_position' => 5,      
                    'supports' => array('title','editor','author','thumbnail','excerpt','comments', 'custom-fields', 'revisions')
                );    

You should use: 'rewrite'=> true
