Problem:
If you're experiencing frequent 404 errors on the translated versions of your pages (EN and IT) on your website, which uses DE as the default language, this might be due to an issue with third-party plugins affecting the rewrite rules.
Solution:
We recommend trying the following steps to potentially resolve this 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');<br />function fix_rewritebase($rules){<br />    $home_root = parse_url(home_url());<br />    if ( isset( $home_root['path'] ) ) {<br />        $home_root = trailingslashit($home_root['path']);<br />    } else {<br />        $home_root = '/';<br />    }<br />  <br />    $wpml_root = parse_url(get_option('home'));<br />    if ( isset( $wpml_root['path'] ) ) {<br />        $wpml_root = trailingslashit($wpml_root['path']);<br />    } else {<br />        $wpml_root = '/';<br />    }<br />  <br />    $rules = str_replace("RewriteBase $home_root", "RewriteBase $wpml_root", $rules);<br />    $rules = str_replace("RewriteRule . $home_root", "RewriteRule . $wpml_root", $rules);<br />  <br />    return $rules;<br />}

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