“Fatal error: Class ‘DOMDocument’ not found in /var/www/html/omeka_archive/application/libraries/Zend/Xml/Security.php on line 82”
And one of my neatline exhibits reset itself. I think I can fix it, but can’t try because I can’t get to it in the dashboard. It should have a custom layer as background and begin zoomed in to the center of the map.
“Fatal error: Class ‘DOMDocument’ not found in /var/www/html/omeka_archive/application/libraries/Zend/Xml/Security.php on line 82”
That error indicates that you don’t have the necessary PHP extensions installed. This one is the “dom” extension, (sometimes just provided by a php-xml package in some distributions).
The broken dashboard looks like it’s an HTTP/HTTPS issue: you’re loading the site over HTTPS, but it thinks you’re using HTTP and is generating links accordingly.
This can happen if you’re handling HTTPS at a higher layer than Omeka can “see” so we then have trouble detecting whether to use HTTPS URLs.
