 * Hi,
 * We’ve checked multiple times and haven’t encountered this issue. It might be 
   related to the version of PHP installed on your server.

 * Your discuz plugin does not yet support the PHP 8.2 version and I have to go 
   down the rank of the PHP version.
 * Then I have to use the PHP version which version?

 * Hi,
 * This is not related to the PHP version. The `str_rot13` function has been included
   since PHP 4.0. In the error log, the function name appears in uppercase, which
   is incorrect—it should be lowercase. You may have made some changes via FTP.
 * Anyway, please uninstall the wpDiscuz plugin, then reinstall it.
 * For more information, visit: [https://www.php.net/manual/en/function.str-rot13.php](https://www.php.net/manual/en/function.str-rot13.php).

 * I follow your advice to reinstall. Error messages always appear when activating
   your plugin in the PHP version 8.2 version.
 * Can you help me so that I can use WPDISCUZ in the PHP 8.2 version I currently
   use the PHP 7.4 version and your WPDISCUZ is functioning. But I want to increase
   my PHP to version 8.2, I don’t know how to correct that mistake.

 * PHP 8.2 compatibility issue is fixed, my sites can be updated to PHP 8.2 without
   any error messages. Thanks for your feedback so far.
