Hello, I use WPDiscuz and after going to php version 7.2. the error_msg.png error message is displayed. The error is caused by the mcrypt_encrypt php function. After replacing the openssl_encrypt, everything is OK.
The 7.2 PHP version of your server doesn't have all necessary extensions. Please read this answer: https://stackoverflow.com/questions/2604435/fatal-error-call-to-undefined-function-mcrypt-encrypt/#answer-2604474
Warning: This function has been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged. See http://php.net/manual/en/function.mcrypt-encrypt.php
Pavel,
We've already mentioned here that you're probably using an old version.
This problem has been fixed. Please make sure you use the latest 1.0.4 version of wpDiscuz Online users addon.
Yes! Now it's okay. Thank you and sorry for the stupid question.
Have a nice day
