Failure installing SquirrelMail

I have installed SquirrelMail from the available scripts in Virtualmin and it was ok, but when I try to access to the page it appears a blank page:
https://tse-iberica.es/correo/

Can anyone help me?
System Information:
OS type and version : Ubuntu 24.04.4
Webmin version : 2.111
Virtualmin version : 7.10.0
Related packages : SquirrelMail 1.4.22

 Install Script
In domain tse-iberica.es

The PHP Pear modules DB are required, but Webmin's Pear module is not available to install them - proceeding anyway.
