[Discuz] The website prompts Oops! Systemfilelost: class/class_mysqli.php unable to access the forum or enter a wrong password. multiple attempts are prohibited.

1. An Oops prompt is displayed when you open the website! System file lost: class/class_mysqli.php cannot access the Forum

Open the Discuz project and Oops appears! System file lost: class/class_mysqli.php cannot access the Forum. For example, there are many causes, such as upgrade failure and migration.

Except that the Mysql database is not connected successfully, you can directly modify the code.

Open source \ class \ class_core.php and find the throw new Exception ('oops! System file lost: '. $ filename);, change it to return false;

Refresh and enter the Forum normally.

2. Failed Attempts due to incorrect passwords

During Discuz debugging, if a user's password or root password is forgotten for multiple attempts, it will take 15 minutes to try again after five attempts.

You can delete the error attempt record in the Discuz database to continue the attempt:

For the password of the forum and Management Panel, change the count field in the pre_common_admincp_session table from 5 to 0.

For the ucenter user management center password, convert the count field in pre_ucenter_failedlogins from 5 to 0
