Class 'DOMDocument' not found error in Drupal 7
Thought of trying out Drupal 7 after a long time, as much as I had used Drupal 6, I was expecting Drupal 7 to work out of the box for a system which was previously running Drupal 6.I noticed that, for some reason, there were these error messages in my httpd logs: [Wed Jul 25 17:40:13 2012] [error] [client 127.0.0.1] PHP Fatal error: Class 'DOMDocument' not found in /home/ausmarton/Public/website/drupal-7.7/modules/filter/filter.module on line 1041 Now, since I had worked quite a bit with version 6, I knew that all that needs to be done was this: yum install php-xml and /sbin/service httpd reload And it did work! Well, so it looks like besides the usual php extensions like php-gd, php-mysql and others, Drupal 7 also needs php-xml to be able to work properly. EDIT: I've tried this with PHP 5.3.11 on Apache 2.2.21.
