So, I've installed Omeka multiple times in the past on my machine along with utilizing multiple plug-ins and it's always worked fine... except this time. So far, I only have the CSV Import 2.0.3 plug-in installed and when I click on the tab in the Admin Dashboard, I get this error:
Fatal error: Class 'DOMDocument' not found in /var/www/html/omeka/application/libraries/Zend/Xml/Security.php on line 81
I have no idea what to do with this. Please help!
