XSL extension not installed

I would like to use the ViewInBrowser plugin for my PHPlist, but when I add it I just get an error at the bottom of the plugin details saying:

Dependency check Plugin can not be enabled.
Failure on system requirement XSL extension installed

And the plugin is installed but cannot be enabled. Can someone provide some insight on this issue? I do not write in PHP and I haven’t been able to figure out a solve for this issue on my own. Thanks in advance for any help!

@Samv You need to enable the php XSL and XML extensions. If your hosting account has CPanel then you might be able to do it through there.

Otherwise, if you don’t know how to do this, then you will need to raise the issue with your hosting company or system administrator.

Thanks for your help I really appreciate it!
