[TYPO3-english] RTE htmlarea bug in typo3 4.7.14

[PIT Solutions]

Hi All,

I've upgraded my typo3 installation form 4.0.13 to 4.7.14. All the functionalities are working good except RTE html area.
When we try to edit an RTE, it displayed an error like this;

"Fatal error: Class 'DOMDocument' not found in /typo3/sysext/rtehtmlarea/extensions/MicrodataSchema/class.tx_rtehtmlarea_microdataschema.php on line 128 ".


How can I fix this. Please help me.

With regards,
Arun Chandran.
