Class 'DOMDocument' not found

[TonyQ]

Trying to load a saved template into a new campaign ... when I choose the saved template I get this error :

Error 500!
Class 'DOMDocument' not found

Any Suggestions welcomed ...

@TonyQ - Seems your PHP install is either missing the DOM extension, or somehow the class DOMDocument has been disabled.
You can look in backend > misc > php info and search in page for "DOMDocument" and see if you get any results.
