 * Hi,
 * If I activate the “React Settings UI function”, the setting page displays incorrectly.
   So I deactivate it, and come across a fatal error:
 *     ```wp-block-code
       Error Details=============An error of type E_ERROR was caused in line 304 of the file /www/wwwroot/tp6r8.xxx.com/wp-content/plugins/seo-by-rank-math/includes/settings/titles/post-types.php.

 * Hello [@luislu](https://wordpress.org/support/users/luislu/),
 * Thank you for contacting Rank Math support.
 * From your other topic, we noticed that you’ve used Loco Translate to translate
   our plugin. It looks like some placeholders, such as **%s** or **%1$s**, were
   also translated in the `.po` file. Please note that these placeholders should**
   not** be translated or modified; they need to remain exactly as they are.
 * We recommend editing your translation file and correcting the affected strings
   by keeping the placeholders intact. For example, `%1$s` must stay `%1$s` in the
   translation.
 * Once you’ve updated the file, please clear your cache and check again.
 * Let us know how that goes. Looking forward to helping you.

 * I deleted all the extra translation files and now it’s back to normal. Expect
   the official version of Chinese translation to go online as soon as possible.
