I tried to save a new .htaccess I tried to deactivate most of the plugins that I have installed before Polylang. * Actually, polylang works fine before, probably due to certain plugin have a new update or maybe other issue. * Thank you so much for helping. * smile, * [Nabil](https://wordpress.org/support/users/nabil_kadimi/) * (@nabil_kadimi) * [13 years, 4 months ago](https://wordpress.org/support/topic/plugin-polylang-404-errors-with-postname-permalinks/page/2/#post-2746959) * Resaving the permalinks solved the issue for me. * Don’t forget to clear cache if you have any caching plugin installed. * [Nyanabhadra](https://wordpress.org/support/users/nyanabhadra/) * (@nyanabhadra) * [13 years, 4 months ago](https://wordpress.org/support/topic/plugin-polylang-404-errors-with-postname-permalinks/page/2/#post-2746960) * Dear Nabil, * Thank you so much. I have figured it out the problem long time ago. * In the Settings of Polylang, I chosed this * Keep /language/ in pretty permalinks. Example: [http://eiab.eu/language/en/](http://eiab.eu/language/en/) * with smile from Germany! * [LukaszWiecek](https://wordpress.org/support/users/lukaszwiecek/) * (@lukaszwiecek) * [13 years, 4 months ago](https://wordpress.org/support/topic/plugin-polylang-404-errors-with-postname-permalinks/page/2/#post-2746961) * Hello, * I found the cause of the problem. The functions.php file had code that changed the links to the authors of /author/ to /autor/ * ``` add_action('init', 'author_rewrite'); function author_rewrite() { global $wp_rewrite; $wp_rewrite->author_base = "autor"; $wp_rewrite->flush_rules(); } ``` * After removing this code, everything works fine 🙂 * Can we somehow accept this change links to sites with plug Polylang authors? * Best regards! * Plugin Author [Chouby](https://wordpress.org/support/users/chouby/) * (@chouby) * [13 years, 4 months ago](https://wordpress.org/support/topic/plugin-polylang-404-errors-with-postname-permalinks/page/2/#post-2746962) * I can’t make anything with plugins and themes which use flush_rules in such a bad way. This function here is executed at every page load and one should *never* do this. [http://codex.wordpress.org/Rewrite_API/flush_rules](http://codex.wordpress.org/Rewrite_API/flush_rules) * Just comment the line `$wp_rewrite->flush_rules();` and you will be able to use the author base you want (go to settings->permalinks and click on ‘save changes’ to manually flush rules). * If a plugin or a theme want to programmaticaly flus rules, it should make it at activation and deactivation.
