T4 Framework causing issues.

HI,
After upgrading to Joomla 5.4.2, I get this error. Please assist:
0 Call to undefined function T4Admin\dom_import_simplexml()

You must enable dom and simplexml in your PHP settings.
If you don't have access to these settings, you'll need to ask your host.

madhouse The host reported - The do and simplexml extensions are already enabled on the PHP Version.

madhouse You can check in System Information in backend of your website: /administrator/index.php?option=com_admin&view=sysinfo

and see that DOM extension is not there

Kindly check with your hosting provider again.
