Hello, enter the installation mode to check what is the problem, and replace 135roundcubemail.com with your domain name.
Modify this file:
/www/wwwroot/135roundcubemail.com/config/config.inc.php
Add the following:
$config['enable_installer'] = true;
Then browser access, and finally check what is the reason, unable to connect to the database.
Is the database running? Are the username and password OK?
http://135roundcubemail.com/installer/index.php
phpmyadmin This is normal. The browser does not trust it and click send.
Check the php version of phpmyadmin, the phpmyadmin of the panel does not support php8.1, try to replace it with php7.4
phpmyadmin of openlitespeed does not support ssl for now
