Discuz7.2: the backend reports an http500 error. recently, the forum was infected with a Trojan. after being cleared, the system reports an http500 error when logging on to the backend. a similar problem has occurred before, but it is OK when ulimit is set, but this time it won't work. please help me solve it! Thank you. ------ Solution ------------------ set directory permissions. do not grant write permissions to non-upload directories, or grant execution permissions to upload directories! The error http500 is reported in the discuz7.2 background.

Set directory permissions. do not grant write permissions to non-upload directories, and do not grant execution permissions to upload directories,
Less open services!
