PHP extension 'XSL' is not installed

If you get the error message 'PHP extension 'XSL' is not installed' when you connect to the evqueue site on your local server and you know that you installed the correct php-xsl module then check your php.ini file for apache2.
On my system with php-7.3 install it was located at:
/etc/php/7.3/apache2/php.ini
In this file look for the line:
;extension=xsl
and change this to:
extension=xsl
If you restart apache2 service and retry it should now work

Which distro are you using ? In debian this should be done automatically when installing the php-dom package.
