MasterStudy LMS modifiying htaccess rewriting rules

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're using the MasterStudy LMS plugin recommended by WPML and notice that your website becomes inaccessible due to htaccess modifications, this might be relevant to you. The issue arises when third-party plugins frequently call the

flush_rewrite_rules(true)

function, leading to unwanted changes in the htaccess file.
Solution:
We recommend following these steps to address the issue:
1. Ensure you back up your site for safety.
2. Insert the following code into the functions.php file of your theme:

add_filter('mod_rewrite_rules', 'fix_rewritebase');
function fix_rewritebase($rules){
    $home_root = parse_url(home_url());
    if ( isset( $home_root['path'] ) ) {
        $home_root = trailingslashit($home_root['path']);
    } else {
        $home_root = '/';
    }
   
    $wpml_root = parse_url(get_option('home'));
    if ( isset( $wpml_root['path'] ) ) {
        $wpml_root = trailingslashit($wpml_root['path']);
    } else {
        $wpml_root = '/';
    }
   
    $rules = str_replace("RewriteBase $home_root", "RewriteBase $wpml_root", $rules);
    $rules = str_replace("RewriteRule . $home_root", "RewriteRule . $wpml_root", $rules);
   
    return $rules;
}

3. Re-save your permalinks from the Settings >> Permalinks page by pressing the Save Changes button.
4. Clear all types of caches including site/server, plugin, CDN, and browser caches.

adilB-5	Background of the issue: Hello, I am using the plugin MasterStudy LMS that WPML is recommending and supporting as per here: https://wpml.org/plugin/masterstudy-lms-learning-management-system/ https://wpml.org/plugin-functionality/lms/ When I use this plugin it modifies the htaccess and my website becomes inaccessible. Here is what is modified: RewriteEngine On RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] is replaced by : RewriteEngine On RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteBase /en/ RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /en/index.php [L] Also in this page WPML says this is a known issue and is corrected in recent WPML update , but it's not the case as problem is still happening : https://wpml.org/forums/topic/htaccess-rewrite-2/ Symptoms: Questions:

Noman WPML Supporter since 06/2016 Languages: English (English ) Timezone: Asia/Karachi (GMT+05:00)	Hi, Thank you for contacting WPML Support. Sorry for any confusion, this issue arises due to some third party plugins when they call flush_rewrite_rules(true) function too often and it can only be fixed directly by the plugin author. As a quick workaround, could you please follow the below steps and see if this resolves the issue: 1. Please take a backup of your site first for safety reasons. 2. Please add the below code in the functions.php file of your theme: add_filter('mod_rewrite_rules', 'fix_rewritebase'); function fix_rewritebase($rules){ $home_root = parse_url(home_url()); if ( isset( $home_root['path'] ) ) { $home_root = trailingslashit($home_root['path']); } else { $home_root = '/'; } $wpml_root = parse_url(get_option('home')); if ( isset( $wpml_root['path'] ) ) { $wpml_root = trailingslashit($wpml_root['path']); } else { $wpml_root = '/'; } $rules = str_replace("RewriteBase $home_root", "RewriteBase $wpml_root", $rules); $rules = str_replace("RewriteRule . $home_root", "RewriteRule . $wpml_root", $rules); return $rules; } 3. Please re-save the permalinks from the Settings >> Permalinks page by pressing the Save Changes button. 4. Please delete all sorts of caches on your site/server cache if any / plugin cache / CDN cache, clear the browser cache, and then see if it resolves the issue afterward. Here you can see more details about it: https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/ Please let me know the results, Thank you for your cooperation
